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:
KWin used to do a quirky trick to send key events to the topmost QQuickItem
rather than things going to the activeFocus item.
Sending it to the window previously would have failed as the window
didn't think it was active.
Since 66986d4afd we can just let the
window process the events in a normal QtQuick manner.

Summary:
On build.kde.org all tests loading scripted effects are failing. This
seems to be because the effects are not installed.
To make this work, this change introduces the following changes:
* scripted effects are copied to ${build}/bin, like all binaries
* the test sets XDG_DATA_DIRS env variable to point to ${build}/bin
This change also needs to be added to further tests once this is
accepted. Furthermore it could be considered whether KPackageLoader
should consider the QCoreApplication::applicationDirPath in addition to
the GenericDataLocation. This would make KPackageLoader work much better
in a build tree only setup.
Test Plan: Test passes locally, obviously not tried on build.kde.org

Summary:
So far KWin did not re-evaluate the window rules when the Client's
window class changes. Window class is the main (static) feature the rule
selection is based on. For dynamic changing mapping features like caption
KWin does re-evaluate the rules.
The reason for KWin to not evaluate when the class changes is that KWin
expects the class not to change. From ICCCM section 4.1.2.5:
> This property must be present when the window leaves the Withdrawn
> state and may be changed only while the window is in the Withdrawn
> state. Window managers may examine the property only when they start
> up and when the window leaves the Withdrawn state, but there should be
> no need for a client to change its state dynamically.
Unfortunately there are prominent applications such as Spotify which
violate this rule and do change the window class dynamically. While this
is a clear ICCCM violation there is nothing which really forbids it (may
not != must not) and nothing which forbids KWin to react on changes.
As also libtaskmanager started to react on it, it makes sense to also
hook up the required bits for window rules. After all KWin detects
changes to the window class for some time already and has the
functionality to evaluate the rules. So all there is, is one connect
which improves the situation for our users, while at the same time it
should be rather risk free. If a setup window rule breaks after this
change it's due to the client not being ICCCM compliant.
Test Plan:
I don't use any of the affected applications, so it's only
tested with the new added unit test.

* For some reason, if a window goes deleted, it will be kept around as
long as the Snap Helper effect needs it (visually, it doesn't look
good).
Among other changes:
* Use variables to store color and width of grid lines;
* Use new connect syntax;
* Port to TimeLine;
* Fix coding style in some places.

Summary:
862bf0f153 introduced a regression(sorry
for that): if you close a confirmation dialog(with the Scale effect and the
Dialog Parent effect being enabled), the main window(s) will flicker.
That flickering happens because the C++ version of the Scale effect and
AnimationEffect unref deleted windows in different places. AnimationEffect
unrefs deleted windows in prePaintScreen, which btw is not the best
place to do that. The C++ version unrefed windows in postPaintScreen.
So, when the Scale effect has finished animating the main windows, it
will unref them, but windowDeleted signal won't be emitted immediately.
Which means that the Dialog Parent won't be able to delete corresponding
animations on its side and main windows will be painted for a single
frame.
This change addresses flickering by adjusting prePaintWindow in
AnimationEffect so deleted windows won't be painted if none of
animations keeps them alive.
Test Plan:
(make sure that both the scale and the dialog parent effect are enabled)
* Go to System Settings > Application Style > Window Decorations;
* Select a decoration that is different from the current;
* Close the system settings window (don't click "Apply" button);
* When a dialog is shown, click "Discard" or "Apply" button.

If you activate the Present Windows effect and then the Desktop Grid,

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: 364709
BUG: 380865
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.
