Summary:
Some old themes have the flag set and also a style which expects the
borders to be stretched. Given that the documentation on techbase
describes widgets/glowbar still as "a frame without a prefix", one also
would assume that all the optional hints (which make sense) still apply.
Even more, the Air & Oxygen themes have the hint also set, though for
their rendering it makes no difference.
The small code needed seems worth the unbreaking of old themes as well
as giving theme creators another variable of freedom for their styles.
Test Plan:
Glow bar still works on all corners and edges with all themes as before,
though rendering now as expected for themes which have the
"hint-stretch-borders" set.

This reverts commit 1e2a0028c3.
Unfortunately, we can't move clients from the above layer to the normal
layer because some of those clients have to be visible when showing
desktop, one such client for example is krunner.
CCBUG: 406101
Summary:
This is the initial implementation of a DRM backend based on the EGLDevice,
EGLOutput, and EGLStream extensions, supporting NVIDIA graphics hardware using
their proprietary driver. The new backend will be used if the environment
variable KWIN_DRM_USE_EGL_STREAMS is set. On initialization, it will attempt to
create an EGLDevice based on the DRM device currently in use and create
EGLOutputs and EGLStreams for any attached displays. These are used to control
presentation of the final composited frame. Additionally, it will register the
wl_eglstream_controller Wayland interface so that native EGL windows created by
clients can be attached to an EGLStream allowing buffer contents to be shared
with the compositor as a GL texture.
At this time there are two known bugs in the NVIDIA driver's EGL implementation
affecting desktop functionality. The first can result in tooltip windows drawn
by plasmashell to contain incorrect contents. The second prevents KWayland from
being able to query the format of EGLStream-backed buffers which interferes
with the blur effect. Fixes for both of these are currently in development and
should appear in an upcoming NVIDIA driver release.
Additionally, hardware cursors are currently not supported with this backend.
Enabling them causes the desktop to intermittently hang for several seconds.
This is also likely a bug in the NVIDIA DRM-KMS implementation but the root
cause is still under investigation.
Test Plan:
On a system with an NVIDIA graphics card running a recent release of their
proprietary driver
* Ensure the nvidia_drm kernel module is loaded with the option "modeset=1"
("# cat /sys/module/nvidia_drm/parameters/modeset" should print "Y")
* Ensure EGL external platform support is installed
https://github.com/NVIDIA/eglexternalplatform
* Ensure KWin was build with the CMake option
KWIN_BUILD_EGL_STREAM_BACKEND=ON (this is the default)
* Start a plasma wayland session with the environment variable
KWIN_DRM_USE_EGL_STREAMS set
* Ensure output from KWin OpenGL initialization indicates the NVIDIA EGL
driver is in use (as opposed to Mesa / llvmpipe).
* Desktop should be fully functional and perform smoothly.

Summary:
Since QPA only performs off-screen rendering, it does not require an EGLConfig
that supports any particular surface type. Currently it requests a config
supporting window surfaces, however the EGLDeviceEXT platform, which is the
basis of the EGLStream back-end used with the proprietary NVIDIA driver, does
not support such surfaces resulting in eglChooseConfig not returning any valid
configs when that back-end is in use. Since QPA doesn't actually create any
window surfaces, it should be fine to remove this restriction to allow it to
initialize properly with the EGLStream back-end.

Currently there is no any good reason for keeping ScopedDrmPointer;
providing our own deleter for QScopedPointer would make more sense.
Given that we already have type that acts as a scoped pointer for drm
objects we can improve it a bit and make simpler, e.g.
DrmScopedPointer<drmModeConnector> connector;
is much simpler than
ScopedDrmPointer<_drmModeConnector, &drmModeFreeConnector> connector;

Summary:
Currently popups get positioned once at the initial configure, to set
the correct size and again when they are mapped.
Toplevels are currently only positioned when they are mapped. This works
for all cases where the the toplevel defines its own size, but not if
the window should have an initial size set by the placement strategy or
window rules. Most notably the maximised placement strategy used on
plasma mobile.
Being out of sync and resizing later currently causes a positioning bug
when plasma mobile is used with XdgShell.
This patch repositions all top levels that don't have a position set
through the plasma interface.

Summary:
When resizing a window particularly from the left side, we need to
co-ordinate moving the window with when we get the resized buffer.
The code in AbstractClient::handleMoveResize checks
isWaitingForResizSync to make sure we never send more than one resize
request at a time to keep that in sync.
This makes sense on X and wl_shell_surface, but not on XDGShell where we
can track which resize events have been handled by the client.
ShellClient already keeps a stack of our pending configure requests and
handles everything appropriately, we don't need to block.
This results in a smoother dragging experience and avoids a potential
deadlock currently seen when a client may not reply to a no-op configure
request.

Summary:
Qt scaling and kwin on X11 is never going to work so it is disabled.
However, Qt uses multiple environment variables for subtly different
internal things. We don't set QT_SCALE_FACTOR in Plasma, using different ones.
An XFCE user was setting this, which kinda makes sense if your DE doesn't
have an appropriate UI.
I don't think it's relevant for main_wayland as wl_output.scale should
trump the environment variable.

This particular crash was probably cased as we have a new window type in
Plasma OSD, which does not set BypassWindowManager in Qt window flags.

Summary:
The NVIDIA implementation of glXSwapBuffers will, by default, queue up
to two frames for presentation before blocking. KWin's compositor,
however, assumes that calls to glXSwapBuffers will always block until
the next vblank when rendering double buffered. This assumption isn't
valid, as glXSwapBuffers is specified as being an implicit glFlush,
not an implicit glFinish, and so it isn't required to block. When this
assumption is violated, KWin's frame timing logic will
break. Specifically, there will be extraneous calls to
setCompositeTimer with a waitTime of 0 after the non-blocking buffer
swaps, dramatically reducing desktop responsiveness. To remedy this,
a call to glXWaitGL was added by Thomas Luebking after glXSwapBuffers
in 2015 (see bug 346275, commit
8bea96d701). That glXWaitGL call is
equivalent to a glFinish call in direct rendering, so it was a good
way to make glXSwapBuffers behave as though it implied a glFinish
call.
However, the NVIDIA driver will by default do a busy wait in glFinish,
for reduced latency. Therefore that change dramatically increased CPU
usage. GL_YIELD can be set to USLEEP (case insensitive) to change
the behavior and use usleep instead. When using the NVIDIA driver,
KWin will disable vsync entirely if GL_YIELD isn't set to USLEEP
(case sensitive, a bug in KWin).
However, the NVIDIA driver supports another environment variable,
__GL_MaxFramesAllowed, which can be used to control how many frames
may be queued by glXSwapBuffers. If this is set to 1 the function
will always block until retrace, in line with KWin's expectations.
This allows the now-unnecessary call to glXWaitGL to be removed along
with the logic to conditionally disable vsync, providing a better
experience on NVIDIA hardware.
