When finishing interactive resize operation, the move resize geometry is
already good and the client should have sent the corresponding configure
event. So, this moveResize() call is redundant.
This change moves code that is responsible for quitting maximized
horizontally or vertically mode to the start of the interactive resize
operation. It makes handling of MaximizeFull mode consistent, and it
kills one moveResize() call at the end of the interactive resize
operation, which is good because it makes simpler handling of resizing
aspect ratio aware windows on wayland.
However, in order to make resizing of aspect ratio aware windows good
for real, we will need to augment configure events with gravity info.
On Wayland, the move resize geometry and the frame geometry are
completely out of sync.
This change synchronizes emitting of the clientStepUserMovedResized
signal to the move resize geometry changes.
It simplifies code of InternalClient and XdgSurfaceClient, and makes
adding support for other shell surface protocols easier as there's less
boilerplate stuff that you would need to take care of.
With internal clients and xdg-shell clients, geometry updates occur in
asynchronous fashion when interactively resizing the window.
As is, performInteractiveMoveResize() will call resize() if the move
resize geometry is different from the current frame geometry. This can
result in kwin sending excessive configure events.
With this change, kwin will send less configure events during
interactive resize.
It's not practical, regular users don't care about window geometry. One
could argue that it can be useful for creating window rules, but window
rules kcm pulls relevant properties from kwin.
If needed, one can reimplement this feature as a QtQuick script that creates
an overlay window positioned above the window that is being interactively
moved or resized.
Instead of only allowing the current format, send the default tranches modified
to only contain formats and modifiers suitable for scanout.
In order to not fail when we can't do direct scanout with a given format
(because that may require a modeset, which we don't allow), keep a blacklist
of attempted formats and modifiers for the current client.
The fixed size of 1080p makes windows change their size and place. To
prevent that from happening, make the placeholder screen the same size
as the last disconnected screen.
This is not a bullet proof solution, only a fast one. Ideally KWin
should remember the window layout on a given monitor setup and restore
it when reconnected.

This makes the Scene less overloaded and it's needed for things such as
render layers.
In hindsight, it would be great to merge checkGraphicsReset() and
beginFrame(), e.g. make beginFrame() return the status like in QRhi or
VkSwapchain. If it's OUT_OF_DATE or something, reinitialize the
compositor.
Same as real hardware wl_keyboard, key should be sent before modifier
change. For example, Left Ctrl press and release should produce
key events in the order of Control_L and Control+Control_L.
When creating the texture containing the window decorations, the drawing
code now directly handles the rotation for the left and right
decoration, instead of rotating the image after it has been drawn.
The padding, to prevent texture bleeding, is now a fixed value instead
of being scaled. With this change, there are no longer visual artifacts
for window decorations with rounded corners, when the scaling value is
fractional.
On X11, if buffer age is unsupported, kwin can do some quirks like
copying parts of the front buffer to back buffer to avoid repainting the
whole screen.
Currently, the copying is performed in the opengl scene, which is not
perfect because it makes the scene responsible not only for painting the
scene but also some low level platform specific shenanigans.
This change moves the copying step to the glx and egl backends. It
simplifies the opengl scene, makes it less overloaded and more open to
changes, but it also duplicates code, which is not ideal. However, given
the de-facto deprecated state of the X11 platform, it's sort of acceptable
as the main focus is now on wayland session and the things that are
needed to make it fly as expected.
It can help clients predict how KWin will react. Sometimes, the noise of
seeing a virtual keyboard pop up is reason enough not to focus an input
field.
Observed in kdevelop, that isEnabled() could be false when switching
between different tabs with Ctrl+Tab. But Qt may still call show()
if you click on the texteditor widget. This leads to isEnabled == false but
setActive(true) is called. This causes kdevelop in a usable state because
keyboard grab will be created and no key event will reach application
because isEnabled == false. Under normal circumstances, key will reach
widget first and triggers another text_input_v2 enable to make input
method work properly.
text-input-v3 does not have preedit styling, instead, it can only
specify the range of cursor. Try to keep track of any
highlight/selection style range and combine them together. If it matches
the cursor position, use it as the cursor range.
Ctrl+Meta+D is already taken by the Minimize All script. "W" in Meta+W
stands for "window". Meta+O wasn't chosen because it's one of a
finger-stretcher.

This commit makes 10 bits per color channel the default color depth, which
should reduce banding on outputs that support color formats with more than
8 bits per color channel. In order to support this the commit also removes
the dependency of the EglGbmBackend on a specific format and EglConfig and
instead makes those per-Output properties.
Qt usually request InputMethod::hide() upon unfocus, but
InputMethod::show() is actually never called if focus transfer is done
by keyboard, which leads to a permanent disabled input method state.
It can be easily reproduced with a window with two text field, e.g.
QFileDialog, by pressing tab to switch the focused widget.
The semantics of hide/show should not deactivate the input method.
Instead, it should simply hide/show the input panel. Also it should not
be a hard request for input method to permanently hide the window. When
input method asked to show it again, the input panel window should be
shown.
zwp_input_method_v1 has some different semantics comparing to
text-input-v3. There is no way to indicate that "clear preedit" with
zwp_input_method_v1. In some client (Namely, Gtk), receiving an empty
preedit string will also trigger replace selection action. For example,
focus into address bar in firefox will automatically select the URL in
the address bar, and a following empty preedit string will clear the
selection which is not desirable.
To avoid such behavior, simply send an empty "done()" to clear text
input v3 preedit if preedit is empty.
This allows us to decouple effects more and reduce the number of random
odd build failures on freebsd. Besides that, it provides more fine
grained control over logging, for example, one could select log output
from some concrete effect, etc.
This may be problematic for certain client, e.g. firefox, and cause
input always reset after any key press. Also, sending reset on an
activate also does not match the text input v3 semantics.
zwp_input_method_v1 does not support generic double buffered event.
deleteSurroundingText need to be followed with done().
zwp_input_method_v1 preedit event order is preeditCursor,
preeditStyling, preeditString. To align it with text-input-v3 semantices,
send done() after receiving preedit_string() from input method.
Currently, it's possible to have the case where the pointer input device
handler or the touch input device handler thinks that there's a focused
window, but the corresponding focused surface in wayland seat is unset,
because the pointer hovers the server side decoration.
If the server side decoration is destroyed, the input device handler will
fail to update wayland seat's focused surface.
In order to make pointer input device handler and touch input device
handler code more intuitive, this change makes focusUpdate() functions
ignore the decoration.

While finding this to be benficial when working on the activity
switcher I think it makes sense in general to keep focus on the
current client instead of potentially switching away.
KWin does not update activity status when setting `_KDE_NET_WM_ACTIVITIES`
to nullUuid outside of KWin, which causes "All Activities" not working
as expected for KWindowSystem.
`X11Client::activityList` is not kept in sync with
`AbstractClient::m_activityList`. Move `m_activityList` from private to
protected, and use it in `X11Client::readActivities`
