Keith Packard e5a188cb91 present: Signal destroyed flip window with vblank->window == NULL ... This eliminates dereferencing freed window pointers when there is a flip for that window in progress. The flip will complete, and then immediately get undone (as we can't stop an in-progress flip). Remove the vblank->window_destroyed field as we can signal this with vblank->window == NULL instead. Change check to vblank->window == NULL in: present_flip_notify Add check for vblank->window == NULL in: present_vblank_notify present_execute present_flip_notify was also using vblank->window->drawable.pScreen, so stop doing that and use vblank->screen instead.
