This appears to be in the same family as bug 1943406. But rather than being driver-specific it looks like mutter is trying to delete an invalid texture, which will crash differently for each driver.

summary:	- gnome-shell crashed with SIGSEGV + gnome-shell crashed with SIGSEGV in old_intel_region_release() from + old_intel_miptree_release() from intel_free_texture_image_buffer()
summary:	- gnome-shell crashed with SIGSEGV in old_intel_region_release() from - old_intel_miptree_release() from intel_free_texture_image_buffer() + [i915] gnome-shell crashed with SIGSEGV in old_intel_region_release() + from old_intel_miptree_release() from intel_free_texture_image_buffer()
