Summary:
If you switch virtual desktops while krunner is sliding in, then
depending on whether your distro strips assert statements away,
KWin can crash.
The reason why it crashes is the sliding popups effect tries to unref
deleted windows that it hasn't referenced before (if there is an active
full screen effect, then popups won't be slided out, which in its turn
means that we won't reference deleted windows). So, in the end, the
refcount of those windows can be -1. That triggers an assert statement
in the destructor of the Deleted class, which checks whether the
refcount is equal to 0.
Popups are not slided while there is an active full screen effect because
we don't know what the full screen effect does.
This patch adjusts the sliding popups effect so it stops all active
animations when user switches virtual desktops or when a full screen
effect kicks in. We need to do that so the effect won't try to
unreference windows in postPaintWindow.
Visually, it doesn't look quite nice, but for now that's good enough.
A proper fix would be more complex: we would need to make sure that
full screen effects ignore sliding popups (and also maybe docks) and
perform some input redirection.

Summary:
If you activate the Present Windows effect and then the Desktop Grid,
you'll be able to see the close button from PW. The reason for that is
PW doesn't destroy the close button and DG doesn't filter it out.
This patch addesses this problem by syncing DesktopGridEffect::isRelevantWithPresentWindows
with PresentWindowsEffect::isSelectableWindow.
On X11, the close button is filtered by the isSpecialWindow check. On
Wayland, the close button is filtered by the acceptsFocus check.
The proposed solution is kinda hack-ish, but on the other hand, we have
to keep those two methods in sync anyway.
In addition to the close button, notifications won't be displayed too.

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.

BUG: 368811
FIXED-IN: 5.15.0
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.

compositing along with Lanczos scaling are in use since its coordinates will never

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 one wants to drag a maximized window while he or she has enabled both
the Wobbly Windows and the Maximize effect, visual artifacts can be
shown.
When the Maximize effect animates transition from maximize to restore,
some parts of the window can overshoot repaint regions(because of
wobbliness), leaving us with the visual artifacts.
To fix that, we have to take into account current scale and translation
when calculating dirty region in the Wobbly Windows effect.

Summary:
With the Oxygen cursor theme, a visual glitch can appear in the
bottom-left corner of the cursor when the screen is zoomed in.
The reason for that is we're using GL_REPEAT for GL_TEXTURE_WRAP_S
and GL_TEXTURE_WRAP_T. So, when the linear filter samples neighboring
texels in the bottom, it can sample some texels from the top (because of
GL_REPEAT).
To fix that, we have to set the wrap mode to GL_CLAMP_TO_EDGE.

The Track Mouse effect can be toggled either by pressing modifier keys
and moving mouse or by pressing a shortcut. It's not possible to use
the latter and then the former without changing config.
But there is one caveat, in order to use shortcut, you have to uncheck
all modifier keys. This seems to be not very intuitive.
In addition to that, the KCM allows to change shortcut even if there is
some checked modifier.
As the title says, this change makes possible to use both modifier keys
and shortcut to activate this effect without changing config.

(cherry picked from commit 7bfaa6e913)
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.
Test Plan:
* Opened KCM of this effect;
* Changed strength;
* (the KCM window stayed bright after I clicked "Apply" button).

Summary:
The Dim Inactive effect was rewritten mostly to fix most of issues with
it, e.g. after leaving a full screen effect(e.g. Desktop Grid) windows
sometimes are not dimmed back, or when a window becomes inactive there
is no smooth transition, etc.
{F5956124}
//Before: the window is not smoothly dimmed.//
{F5956127}
//After: the window is smoothly dimmed.//
In combination with an effect that animates the disappearing of windows,
e.g. Glide, the rewritten Dim Inactive effect doesn't "flash" windows.
If an active window has been closed, it will stay bright. If an inactive
window has been closed, it will stay dimmed.
Among other changes, the KCM has been re-designed to follow common KCM
design in Plasma:
{F5956128, layout=center, size=full}
The way the rewritten Dim Inactive effect handles flashing/flickering problem can be
reused in the Dialog Parent effect.
