Explicit GPU Synchronization Merged For XWayland

[Forge]

I'm a Wayland fan but from what I understand, multi-monitor seems to be the most problematic feature regardless of DE. Not sure if that's still true since I haven't used Linux and multiple extended displays in years (I've cloned displays in the past year but that's not really the same thing).

4K 144HZ 43" on the wall, 1440p 165Hz down here on my desk, both working correctly and without issues under Wayland. Under X11, I had so many issues with scaling, refresh rates, window movement and monitor orientation. Under Wayland, it has all "just worked".
