It has been disabled with Mesa for almost half a decade due to false
positives and even if it weren't disabled, it contributes to the startup
time.
The commit message that added the self test doesn't explain why it was
added, but if it was added to detect unstable drivers, it's not worth it.
With an opaque fullscreen window we can be sure that items under it don't
actually require us to repaint. This should yield some small efficiency
improvements and resolves stutter with adaptive sync.

Windows in workspace.clientList() are sorted in the map order. This
means that the minimize all script will try to activate the last mapped
window when unminimizing windows, which is a bit annoying.
This change ensures that the minimize all script doesn't activate wrong
window by minimizing and unminimizing windows in the stacking order.
It's not a bullet-proof solution though, but it should produce good
enough results.
This improves file organization in kwin by putting backends in a single
directory.
It also makes easier to discover kwin's low level components for new
contributors because the plugins directory may come as the last place to
look for. When one hears "plugin", the first thing that comes to mind is
regular plugins, not low level backends.
This ports the nested wayland platform plugin to the InputDevice
abstractions.
Some global handling logic has been simplified to make porting more
straightforward.
The main motivation behind this change is to prepare input abstractions
for virtual input devices so the wl_seat can properly advertise caps or
the cursor getting properly mapped/unmapped when a fake pointer is
added/removed on a system without a hardware mouse connected.
With this, there are three abstractions - InputDevice, InputBackend, and
InputRedirection.
An InputDevice represents an input device such as a mouse, a keyboard, a
tablet, etc. The InputBackend class notifies the InputRedirection about
(dis-)connected devices. The InputRedirection manages the input devices.
Such design allows to unify the event flow for real and virtual input
devices.
There can be several input backends active. For example, the libinput
backend and an input backend that provides virtual input devices, e.g.
libeis or org_kde_kwin_fake_input.
If an output is disconnected, the Workspace will update the
Toplevel.output property for all windows that are on that output, then
it will call AbstractClient::checkWorkspacePosition() to fix window
position.
That may result in some windows partially sticking outside visible area
because AbstractClient::checkWorkspacePosition() has no idea what output
the window was.
This change addresses that problem by delaying updating the
Toplevel.output property so AbstractClient::checkWorkspacePosition()
could pick better window placement.
The role of enabledByDefaultMethod was misinterpreted. It exists only
for kcms so they can display undetermined state. EnabledByDefault should
still be set to a valid value.
Currently, if an output is hotplugged, all windows will be scrambled,
which is highly annoying.
With this change, windows will stick to their outputs if an output has
been connected or disconnected.

Currently, AbstractClient::geometryRestore() is abused to put windows
back on their original screen. It makes window placement more complex
and it breaks restoring initially maximized windows.
It looks weird given the kind of visualization where this text is
displayed.

After the decoration is destroyed, we need to resize XdgToplevelClient
to ensure that the scheduled configure event will have correct size.
As is, xdg-toplevel configure events are delayed. When it's actually the
time to send a configure event, XdgToplevelClient will compute the
requested client size from the moveResizeGeometry().
If the moveResizeGeometry() still includes window decorations, the
window will get bigger.
