Glitches with nvidia driver 470 (optimus render offload) on xwayland with vulkan games

This is a driver bug. We weren’t synchronizing frame presentation with Xwayland correctly which could cause the visual artifacts you’ve been observing. I believe the direct scan-out thing mentioned above was just a coincidence in that it changes the timing of things which could mask the issue. I’ve got a candidate fix which I’m just finishing up testing, I’ll try to get it out as soon as possible. Thanks everyone who provided their data-points here.
