Therefore, we should not try to read freed memory at

A memory leak introduced by 6b58ea8c led to me finding a bigger leak,
which is xwm was calling frame_create() without calling frame_destroy().
This meant that the associated icon_surface was not being destroyed,
leaving the destroy handler for it broken. Here we fix this by calling
frame_destroy() when the window is destroyed and free the reply in
the icon_surface destroy handler.

Do not attempt to set keyboard focus to a surface that has no
wl_resource. The destroy listener hangs off the wl_resource, so if that
is not present, nothing will clean up the pointer when the
weston_surface gets destroyed and it goes stale.
As keyboard_focus_resource_destroyed() sets the focus to NULL, this
patch should be enough to guarantee that the keyboard focus surface will
always have a wl_resource.
I have confirmed the added branch in weston_keyboard_set_focus() can be
hit, but doing so is hard.
My test case has weston/x11 with two outputs, and weston/wayland
--sprawl running on top of that, then closing the parent compositor
output windows one by one. Sometimes it hits, often it does not. Having
the window closing animation enabled may help to hit it.

Destroying an output (wl_surface) can race against the parent compositor
sending wl_keyboard.enter. When this race is lost, wayland-backend
receives wl_keyboard.enter with a NULL wl_surface for the surface it
just destroyed.
Handle this case by ignoring such enter events. Since it is
theoretically possible to follow enter with key events, drop those too.
The modifiers event is sent before enter, so we cannot drop that on the
same condition.
wl_keyboard.leave handler seems to already handle the NULL focus case,
but there is a question if the notify_keyboard_focus_out() call should
be avoided.
This patch fixes a hard to reproduce crash. I was running weston/x11
with two outputs, and weston/wayland --sprawl inside that, then closing
the parent compositor windows one by one. Sometimes it would trigger
this crash.

EGL_IMG_context_priority allows the client to request that their
rendering be considered high priority. For ourselves, this is important
as we are interactive and any delay in our rendering causes input-output
jitter; a less than smooth user interactive. So if the driver supports
setting the context priority, try and create our EGLContext as high
priority. The driver may reject our request due to system restrictions,
in which case it will fallback to normal priority, but if successful it
will reschedule our rendering and all of its dependencies to execute
earlier, especially important when the GPU is being hogged by background
clients.

If AddFB2 ever fails for any reason, we fall back to legacy AddFB, which

modifiers.
This can happen with arbitrary client buffers, condemning us to the
fallback forever more. Remove this, at the cost of an unnecessary ioctl
for users on old kernels without AddFB2; unfortunately, we cannot detect
the complete absence of the ioctl, as the return here is -EINVAL rather
than -ENOTTY.
A check for whether or not the format is valid has been replaced with an
assert, as its callers either check that the format is non-zero, return
a FourCC format code from GBM, or use a static FourCC format.

Conversely, when using Weston through RDP (xfreerdp client), sending
X11 button 4 causes window contents to scroll down and button 5 to be
reported to xwayland clients. The xfreerdp client does not seem to be
the cause of this since scrolling works correctly when connecting to
