mpv suspends the compositor, that deletes the QML driven buttons in the desktop
grid (present windows close button might be affected likewise) and that has
somehow a bad teardown order.
No idea whether to blame QtQuick, MESA or the particular driver - looks a bit
like dri2_dpy or dri2_dpy->core (in
https://cgit.freedesktop.org/cgit/?url=mesa/mesa/tree/src/egl/drivers/dri2/egl_dri2.c)
are 0x0 or dangeling?
=> woraround is to either adda rule that forces MPV to *not* suspend the
compositor (but you'll likely get segfaults on doing that by shortcut as well)
or disable the buttons for the desktop grid and present windows effects.
Chances to check what's going on in egl/drivers/dri2/egl_dri2.c (printf the
pointer positions or similar - ideally it's just a nullptr deref)?
Another possible workaouround in KWin might be to take the buttonviews out of
moc's child/parent related and attempt to deleteLater them - but that's sick.
