Summary:
When using the natural layout algorithm with the fill-gaps option, a small
error (less than one) is introduced in windows' aspect ratio each time they are
enlarged due to floating-point roundoff.
Currently, the algorithm computes the width and height enlargement factors and
then attempts to enlarge in each of the four possible directions, repeating
until it can't enlarge any windows any further. Hence, this aspect ratio error
can be multiplied by up to four. Especially for small, long, and narrow
windows, this can result in a total error of greater than one by the end of
that loop iteration. If this occurs, on subsequent iterations the height
enlargement factor might then be computed as negative violating some of the
core assumptions of the algorithm and resulting in the loop iterating endlessly
until one of the window dimensions overflows, freezing the program for up to
several minutes.
To fix this, the height enlargement factor should be re-computed based on the
new width each time the window is enlarged, ensuring the error introduced in
the aspect ratio never exceeds one.

Test Plan:
The most reliable way to reproduce the freeze seems to be to activate the
desktop-grid effect while a tool-tip window is fading in.
Ensure desktop-grid is configured to use present windows, and that present
windows is configured to use the natural layout algorithm with the fill gaps
option selected.
The freeze is still intermittent, but using this method should be able to be
triggered within about 10 tries without this fix.
After applying the fix, the freeze has never been observed.

Summary:
The Dim Inactive effect expects that the windowClosed signal always
proceeds the windowDeleted signal. But in some cases that's not the case.
If a window gets destroyed before becoming ready for painting, only
the windowDeleted signal will be emitted. In addition to that, KWin will
activate that window, which means we'll probably start a transition for
it.
Because this effect cannot terminate active transitions for such
windows, KWin can crash in postPaintScreen.
This change addresses the crash in postPaintScreen by adding extra clean
up stuff in the windowDeleted slot to make sure that there are no
transitions for deleted windows.
The proper fix would be to not emit windowActivated signal for windows
that are not ready for painting.

Summary:
If a modal window is closed and some alternative effect that animates
the disappearing of windows is enabled(e.g. the Glide effect, or the
Scale effect), the Dialog Parent effect can cause flickering of the
parent window because its animation duration doesn't match duration of
those alternative effects.
Also, if the Fade effect, the Glide effect, and the Scale effect are
disabled, the Dialog Parent will keep the parent window alive for no
good reason.
This change addresses that problem by adding keepAlive property to
`animate` function so scripted effects have more control over lifetime
of animated windows.
If both a modal window and its parent window are closed at the same time
(and there is no effect that animates the disappearing of windows), the
Dialog Parent will stop immediately(because windowDeleted will be
emitted right after windowClosed signal).
If both a modal window and its parent window are closed at the same time
(and there is effect that animates the disappearing of windows), the
Dialog Parent won't reference the latter window. Thus, it won't cause
flickering. I.e. it will "passively" animate parent windows.

On X11, in order to distinguish ordinary windows from combo box popups,
popup menus, and other popups, those effects check whether given window
is managed.
On Wayland, there is no concept of managed/unmanaged windows.
XDG Shell protocol defines 2 surface roles:
* xdg_toplevel;
* and, xdg_popup.
The former can be used to implement typical windows, the ones that can
be minimized, maximized, etc.
The latter can be used to implement tooltips, popup menus, etc. Thus,
that's a good criteria to filter popup windows.

Summary:
The Show Paint effect is useful when debugging repaint regions issued by
effects. The only headache with it is necessity to enable/disable it.
Consider the following workflow:
* Do some change to an effect;
* Compile KWin (or the effect);
* Go to System Settings and enable the Show Paint effect;
* Test effect, check repaint regions, etc;
* Disable the Show Paint effect;
* Go to the step 1.
This workflow is really exhausting. Also, when testing repaints in a
nested compositor, things become quite messy.
Because purpose of this effect is to debug repaints (and because this
effect is not meant for daily usage), I think that's fine to change
how it's activated.
This patch improves the workflow by changing the way how this effect
gets activated. Instead of enabling/disabling it, one can just use a shortcut
to activate or deactivate the effect.

The problem was that effect relied on isManaged() to detect OSDs and notifications, that should be painted on top of the cube. On Wayland, the desktop window itself is not managed, which made it "sticky".
Instead we use isSpecialWindow() check to explicitly make notifications and OSDs sticky.
It still requires fixing Plasma::Dialog, since it does not set isSpecialWindow() flag correctly.

Summary:
Bugs occurred because KWin was not very happy when windows were painted during CubeSlideEffect::paintScreen().
Another issue is that blur, although it was supposed to, did not work at all (haven't found appropriate bug on bugzilla).
As well as background contrast effect.
This patch does the following thing:
- Adopted WindowForceBlur / WindowForceBackgroundContrast logic from SlideEffect, instead of panels/stickyWindows QSets (those become useless anyway)
- Added shouldAnimate code, which determines whether a window should be animated with the cube (i.e. ordinary windows) or should stick (i.e. panels or pinned windows, if corresponding options are checked in the settings)
- It paints an additional non-transformed screen, on which it paints only "sticky" windows. This is done because otherwise KWin would apply blur not behind the OSD, but on the same place on moving cube face.
- (in addition) switched to new Qt5 connect syntax.

Summary:
The Dim Inactive effect sees the world a little bit differently.
m_activeWindow is currently active window that can be dimmed later on.
In most cases, it's the same as effects->activeWindow(). In rare cases,
it can be nullptr, even when effects->activeWindow() is not equal to nullptr
(e.g. when active window is a context menu popup).
canDimWindow is a helper that returns true if a given window should be
dimmed, otherwise it returns false. It has one special case: if a given
window is equal to m_activeWindow, return false. I.e. don't dim active
windows.
Currently, if user changes config of this effect, active window becomes
dimmed.
The reason for that is we hit that special case when deciding whether
effects->activeWindow() should be m_activeWindow.
This change addresses that problem by resetting m_activeWindow so we
don't hit that special case.

them;
(c) mWindowsData should be m_animationsData because other parts of this
effect refer to it as "anim data"(e.g. setupAnimData).
This effect uses its own Location enum class instead of KWayland::
Server::SlideInterface::Location because it would be better to not
depend on platform specific data structures.
As a side effect, this change also fixes QHash abuse. The Sliding popups
effect is still hashing windows twice in prePaintWindow and paintWindow.

The new effect scales windows as they appear and disappear.
As the the most of window animation effects, it is a monolithic effect,

disappearing.
The main difference between the Scale effect and the Scale in effect is
that the Scale in effect only animates windows as they appear. There is
no corresponding "the Scale out" effect, which is odd. Other points that
differentiate the Scale effect from the Scale in effect:
* it is more subtle;

Summary:
The Glide effect should not animate the Application Dashboard because
it's not an ordinary application or a dialog. Same applies to Kickoff,
panel popups, etc.
The most obvious solution would be to add "plasmashell plasmashell"
window class to the blacklist, but we still would like to animate some
of plasmashell's windows, for example, Empty Trash Bin confirmation
dialog (if the trash bin icon is on the desktop).
One could notice that the Empty Trash Bin confirmation dialog, Task
Manager Settings window, and other plasmashell's windows that we want
to animate have decorations. So, we can use that as a heuristic.
Test Plan: Opened/closed the Application Dashboard.

Summary:
If a modal window is near some of screen edges, it will be distorted
in undesired way when it's being animated.
In order to keep perspective distortions invariant, no matter where
the modal window is on the screen, we have to move that modal window
to the origin, scale it, rotate it, translate it, apply perspective projection,
and then move it back.

If both the Glide effect and the Sheet effect are enabled,
they will conflict. Expected behavior would be:
* the Sheet effect animates only modal windows;
* the Glide effect animates the rest of normal windows.
In order to resolve the conflict, the Sheet effect has to grab
modal windows. Because it's quite specialized effect, we have
to ignore whether modal windows have been grabbed by the
Glide effect.

D14582 addresses that problem by adding "ksmserver ksmserver" window

instantaneously disappears, instead of smoothly fading out.

Summary:
There are several reasons why I "re-wrote" the Glide effect:
* it doesn't work correctly because it suffers from undesired perspective distortions: {F5914378}
The worst part is that windows are distorted so much on multiple monitor setups that it's hard to say whether that's glide animation.
* window close animation is not quite intuitive: if the close button is
located at the top and I click it, I would expect that window is
rotated around the bottom edge, not the top; (IMHO)
* it's too much distracting when working on something for quite good
amount of time: e.g. when editing photos, which involves a big number
of different dialogs;
* there are issues with deletion of QTimeLine;
* windows are not gracefully released if some other effect grabs them;
* its code doesn't follow common coding style in KWin.
So, the "new" Glide effect is more subtle, it's possible to have
different rotation edges for window open/close animations, it doesn't
animate special windows(like audio volume feedback), the code is simpler
and readable. Yet, there are some issues with QTimeLine, which are
common to all effects in KWin anyway.

Summary:
When the Sheet effect was written, isModal worked only for Client
windows, not Deleted windows:
bool EffectWindowImpl::isModal() const
{
if( Client* c = dynamic_cast< Client* >( toplevel ))
return c->isModal();
return false;
}
so the Sheet effect had to track windows by using WindowInfo class, e.g.
class WindowInfo
{
public:
bool deleted;
bool added;
bool closed;
};
the biggest drawback of that method is that WindowInfo for each modal kept around
as long as those modals existed. It also was adding little overhead, e.g.
void SheetEffect::paintWindow( EffectWindow* w, int mask, QRegion region, WindowPaintData& data )
{
if( windows.contains( w ) && ( windows[ w ].added || windows[ w ].closed ) )
Things changed with a8160b3c31afa1db24084147ad4ce50cf3c0314a. With that
commit, WindowInfo kept only for modals that are currently being
animated, but isModal still worked only with Client windows, so
IsSheetWindow hack had been introduced.
Long story short: we don't need IsSheetWindow hack anymore because
isModal now works with Deleted windows.

Currently, effects like Maximize, Slide Back have problems with setting

This is wrong. Instead they should either ignore previous state of
WindowForceBlur or refcount forced role.
There's no need for refcounting right now. For example, if several effects
force blur or background contrast, they are most likely in a conflict.
Please notice that the Desktop Grid effect uses the Present Windows
effect only to calculate transformations.
Some other problems with the code that sets WindowForceBlurRole:
* Maximize effect stores previous state of WindowForceBlurRole only
for one window. It ignores the fact that there could be several
active maximize animations;
* Desktop Grid/Present Windows/Slide back don't clean after themselves.
So, after using those effects for good amount of times, memory usage
will bump.

The main problem was that inside the effect there was manualVerticalAngle,
which did not represent the actual rotation angle of the cube during the
animation, but used to calculate the position of the reflection. The actual
angle was calculated on-the-fly and was not exposed outside.
Brief description of what the code does:
- variables currentAngle and verticalCurrentAngle now always represent the
current position of the cube. They are updated when one uses the mouse and
inside the rotateCube() method, which is called in prePaintScreen().
- two queues, animations (used for Start / Stop / Left / Right) and
verticalAnimations (used for Up / Down) are used for scheduling the animations
if i.e. user presses several keys in a row. The code checks whether the last
animation has finished (and thus we need to start a new one) inside
prePaintScreen() and postPaintScreen()
- when the animation starts, code saves the starting position of the cube
inside startAngle, startFrontDesktop and verticalStartAngle variables, which
are used to calculate the actual cube position during the animation later.
This is done by startAnimation() and startVerticalAnimation(), which also
calculates the QTimeLine curves needed for animation

Summary:
KWin's window management powers are not as discoverable as they could be--particularly tiling, which by default has no visible UI and no keyboard shortcuts. Resolving this issue is highly relevant to {T6831}.
This patch re-assigns the {key Meta arrowkeys} shortcuts that are currently used for `move zoomed area` (which are pretty esoteric, infrequently-used actions), adding {key ctrl} to their shortcuts. This allows us to use their valuable {key Meta arrowkeys} for more useful and commonly-used window management actions:
- {key Meta Left}: quick tile window to the left
- {key Meta Right}: quick tile window to the right
- {key Meta Up}: quick-tile window to the top
- {key Meta Down}: quick-tile the window to the bottom
The patch also sets some default shortctuts for minimize and maximize:
- {key Meta PageDown}: minimize window
- {key Meta PageUp}: maximize/de-maximize the window
Test Plan:
Do a clean build
`make test` (no new test failures)
Reboot
Create and log into a new user account
- {key meta up} tiles the active window to the top
- {key meta down} tiles the active window to the bottom
- {key meta left} tiles the active window to the left
- {key meta right} tiles the active window to the right
- {key meta PageDown} minimizes the active window

xcb connection got created (future delayed XWayland startup) the atom is
set to the proper value.

Summary:
This patch caputres from the framebuffer using the framebuffer's
geometry, factoring in scale. We then keep the current normal DPI
framebuffer causing it to downsample there.
This is good because:
- it keeps the code very simple
- it's a performance optimisation. Blurring on 4k is naturally more
expensive than at regular DPI. Downsampling keeps it the same - and you
can't see a difference given it's high DPI and you're going to blur it
anwyay.
- it keeps kernel sizes somewhat resolution independent so it will look
just as blurry across multiple screens.
::doCachedBlur still needs doing.

On Wayland it can happen that a window is still in the stacking order
although it is not visible. This is mostly the case for Plasma windows.
So far the slideback effect did not ignore those windows and as they are
higher in the stacking order than most other windows it blocked the
effect from working once a Plasma panel element got closed.
This change considers a window which has painting disabled in the
stacking order as not usable and thus filters out all those windows.

This change adds global touchpad swipe gestures to the
GlobalShortcutsManager and hooks up the swipe gestures as defined at the
Plasma Affenfels sprint:
* swipe up: Desktop Grid
* swipe down: Present Windows
* swipe left: previous virtual desktop
* swipe right: next virtual desktop
The main work is handled by two new classes: SwipeGesture and
GestureRecognizer. This is implemented in a way that it can be extended
to also recognize touch screen gestures and pinch gestures.
The SwipeGesture defines what is required for the gesture to trigger.
Currently this includes the minimum and maximum number of fingers
participating in the gesture and the direction. The gesture gets
registered in the GestureRecognizer.
The events for the gesture are fed into the GestureRecognizer. It
evaluates which gestures could trigger and tracks them for every update
of the gesture. In the process of the gesture tracking the
GestureRecognizer emits signals on the Gesture:
* started: when the Gesture gets considered for a sequence
* cancelled: the Gesture no longer matches the sequence
* triggered: the sequence ended and the Gesture still matches
The remaining changes are related to hook up the existing shortcut
framework with the new touchpad gestures. The GlobalShortcutManager
gained support for it, InputRedirection and EffectsHandler offer methods
to register a QAction. VirtualDesktopManager, PresentWindows and
DesktopGrid are adjusted to support the gesture.

Summary:
For Wayland windows we can have a sequence of window unmapped
(windowHidden signal) followed by a windowClosed way later when the
application quits. This is for example the case with menus.
The result of this was that the fade out animation triggered when the
application quit showing all the already closed menus again.
This change implements a windowShown and windowHidden handler and
triggers the fadeIn/Out animation on it. If the window gets shown
again the existing fadeOut animation gets cancelled, so that it can run
again.
If a window gets closed for which a fade out animation has been run
already, it's not triggered again, thus ensuring that we don't see
zombie windows.

Summary:
The idea behind this mode is to support applications like spectacle
(see T4458). The calling application passes a file descriptor (created
through e.g. a pipe) and the screenshot effect writes the captured image
into that fd.
The advantage over the existing variant which writes to a file in the
/tmp directory is that this is peer-to-peer between the requesting
application and KWin. No other application can get to that image.
The change also includes setting SIGPIPE to ignore. It showed that when
the reading side already cancelled the read prior to KWin writing out
the image we get a SIGPIPE which results in application termination,
which is not what we want in case of a Wayland compositor. The sigpipe
can be ignored as Qt (and libpng) handles that error just fine at
runtime.

The glide effect tried to not animate any window the SlidingPopups
effect animates. But it detected that in a very crude way. It announced
the KDE_SLIDE atom and checked for windows having that property set.
This has a few disadvantages:
* KWindowEffects::isEffectAvailable gets confused as an effect announces
support for SlidingPopups which doesn't provide SlidingPopups
* The approach can only work for X11 windows
* The approach causes X11 usage in the ctor
With this change the GlideEffect implements a slot for
EffectsHandler::windowDataChanged to detect that the SlidingPopupsEffect
grabbed the window. The X11 atom interaction is removed.

Summary:
When windows get added some effects grab the window and want to be the
only one animating this window. For this the grab roles exists. An
effect being notified later on evaluates the grab state and does not
start the animation.
This process failed due to being dependent on the order the effects are
loaded. Window Added/Closed are signals emitted by EffectsHandler, thus
first come, first serve. The requested effect order does not play into
it.
Due to that it could happen that an Effect which should not animate,
started to animate as the grab was still there.
This change adds the possibility to be notified whenever the window data
changes. A new signal is added to EffectsHandler which is emitted
whenever the windowData changes. The interested effects connect to it
and cancel their (just started) animation for the window.
Adjusted effects are:
* ScaleIn
* Fade
* WobblyWindows
In case of WobblyWindows an additional logical error was fixed that the
animations were only run when an effect grabbed instead of the other way
around.

Summary:
The screenshot methods to blit the screen so far did not capture the
cursor image. But sometimes it is useful to also capture the cursor
image.
This change extends the exported methods to take an optional bool
argument whether to capture the screen. The default is not changed and
still not captures the cursor.

Summary:
On Wayland we do not need the selection. By only creating the
KSelectionOwner on X11 an X11-runtime dependency is removed from the
StartupFeedbackEffect.

Summary:
Desktop Grid has a feature that right or middle clicking a window toggles
the on all desktop state. If that is done for a desktop window, things
obviously start to fail.
KWin internally allows to change virtual desktop for all windows, even
for windows like the desktop or docks. Changing in KWin core is not a
solution.
Thus a special casing in desktop grid is added to disallow the selection
for desktop windows.

FIXED-IN: 5.8.4
Test Plan: Tried right clicking desktop window and other windows.

Summary:
QSpinBox can't handle plural suffixes. Something previously done by
KIntSpinBox.
Using setSuffix(ki18np("pixel", "pixels")).toString() does nothing, as
at the time of conversion we don't know which one to use.
This patch uses KPluralHandlingSpinBox and correct ki18np.
Note, "new" dependency was already linked implicitly in other kwin, but
we need to add it for this KCM.
Test Plan:
Opened KCM (in English) set counter to 1 pixel and 2 pixels.
No longer had a big warning. Also appropriate number of s's appeared.

Summary:
The implementation delegates to the Platform to perform the actual
show/hide of the cursor image.
This replaces the implementation in the zoom effect which so far
directly interacted with xfixes to show/hide the cursor. This is now
provided by the x11/standalone platform. And due to this change the zoom
effect can now properly hide the cursor on platform DRM (wayland) as
well.
Test Plan: Zoom effect on Wayland hides the cursor

Summary:
It can happen that startAnimation is invoked multiple times for a
window. In case it was invoked a second time the previous animation was
not cancelled. This resulted in the set-animation to never end. When
closing a window, it would stay around as a translucent, non-interactive
window zombie.
This change ensures that existing animations get cancelled.

Summary:
There are several effects (screenshot, zoom) which need access to the
cursor image and cursor hotspot. So far these effects used X11
unconditionally to get the cursor which obviously does not work on
Wayland.
This change adds a new class PlatformCursorImage to kwinglobals which
wraps what a cursor is (image and hotspot) and adds a new virtual method
to Platform to provide such a PlatformCursorImage. By default it's the
cursor image the Platform tracks. On X11/standalone platform this new
virtual method is overriden and provides a PlatformCursorImage from X11
using the code previously used in screenshot effect.
Screenshot effect and zoom are adjusted to use the new API instead of
X11.
Test Plan:
Zoom effect tested on Wayland, now gets the proper cursor icon.
X11 functionality not yet tested.

Summary:
The glCopyTex(Sub)Image calls are adjusted to take the per output
rendering into account. In addition contrast effect sets the model view
projection matrix in each call to ensure it's on the correct screen.
Blur probably needs more changes for the cached texture to work, but
it's a start.

Summary:
Adjusts the screenshot effect to mutliple output rendering. In that case
the blit from framebuffer can only get one output. Thus the effect needs
to blit every output and combine the rendering result.

Summary:
For windows the screenshot effect already delayed the rendering into the
next cycle. But for the fullscreen variants which save to a file the
Screenshot effect did try to take the shot directly.
This can be problematic as e.g. the OpenGL context might not be bound at
all. Also this makes it impossible to screenshot multiple screens
together in the Wayland case.
This change delays the DBus replies, schedules the geometry and takes
the screenshot in the next rendering pass. It does not fix the
multiscreen wayland problem yet.

Summary:
The highlight windows effect tried to trigger repaints with the shadow
included by having an hardcoded pixel offset. This of course breaks if
the shadow is larger than the hardcoded value.
The reason presented on why it was done like that is no longer true and
in the effects the actual visible area including decorations and shadows
is available through the expandedGeometry.

Summary:
So far TabBox used highlight windows by passing window ids around through
an X property. This doesn't work on Wayland where we don't have window
ids for our TabBox and the Wayland windows.
This change introduces a new Effect::Feature for HighlightWindows which
the HighlightWindowsEffect provides. The EffectsHandlerImpl has a new
method to highlightWindows which it delegates to that effect if it is
loaded by invoking a new performFeature method.
The TabBoxHandler now passes the highlighting to the effects system
instead of updating the x11 property. Thus this works on Wayland and
at the same time improves the X11 side by no longer having to go through
the property protocol.
Test Plan: Verified that Alt+Tab highlights the windows on Wayland correctly.

Summary:
The new logout design doesn't want to have the vignetting. Thus the
logout effect itself doesn't make any sense any more. All that would
still be used is the logout blur which can also be provided by the
blur effect nowadays for fullscreen windows. As the new logout is a
fullscreen window it should use that one.
The logout effect did one more thing: it kept the vignetting and the
blur once the user selected logout. Now without the vignetting this
would be weird and again doesn't make much sense any more.
So overall I think it's better to just drop the logout effect and use
blur effect in normal way. Neat side advantage: it will also work on
Wayland out-of-the-box.

Summary:
The new effect is based on the mouse click effect and uses the same
rendering code (this could be improved by merging them better).
Unlike mouse click there is no keyboard shortcut needed to activate:
as soon as the effect is loaded all touch points are visualized.
The visualization creates an animated circle for each touch down
position, motion and up position. The ids are tracked and each touch
id gets the same color. The first ten different touch ids get a
different color. As touch ids are stable the first finger will always
have the same color.

Summary:
The Effect class is extended by three new virtual methods:
* touchDown
* touchMotion
* touchUp
The methods return a boolean value so that the events can be filtered
out. E.g. an effect which has also a mouse grab installed wants to
filter out all events, other effects don't need the events exclusively.
This is a difference to how e.g. keyboard and pointer events are handled.
But is more close to how KWin's internal input event passing works and
makes it easier to get touch event: one does not explicitly has to grab
the events. It's also closer to Wayland where all input events are
available.
As a first example the Present Windows effect is adjusted and allows to
activate windows through the touch screen. As much code as possible is
shared with pointer input.

Summary:
A new method to tell the effects system whether the compositor scene
is able to drive animations. E.g. on software emulation (llvmpipe) it's
better to not do any animations at all.
This information can be used by effects to adjust their behavior, e.g.
PresentWindows could skip transitions or effects can use it in their
supported check to completely disable themselves.
As a first step all scripted effects are considered to be unsupported
if animations are not supported. They inherit AnimationEffect and are
all about driving animations.
The information whether animations are supported comes from the Scene.
It's implemented in the following way:
* XRender: animations are always supported
* QPainter: animations are never supported
* OpenGL: animations are supported, except for software emulation
In addition - for easier testing - there is a new env variable
KWIN_EFFECTS_FORCE_ANIMATIONS to overwrite the selection.
