Xwayland initializes glamor on top of an EGL display, but some fatal
exit paths bypass the normal screen close sequence. In particular, this
can happen through xwl_give_up() after the Wayland compositor goes away,
or through ddxGiveUp() after early startup failures such as keymap
compilation failure.
A relevant excerpt from the ASan report:
