Bug description:
[ Impact ]
On dual-GPU systems, gnome-shell may crash in
gbm_surface_release_buffer() during display config changes, like when
rearranging monitor positions.
[ Test Plan ]
1. Find a dual GPU system where both use open source drivers (like Intel +
AMD).
2. Ideally also attach one monitor to each GPU.
3. Open Settings and repeatedly change the monitor layout pressing Apply each
time.
Expect: System does not crash.
[ Where problems could occur ]
Anywhere to do with screen updates since the entire triple buffering
patch has been updated.
