Describe the bug

When running wlroots0.19 on any wayland compositor, framerates drop to 0 and there is massive stutter/lag on mouse input (specifically lmb/rmb, but also massive tearing, ghosting, and general unsmoothness on mouse movement). This is exacerbated but limited to fullscreen clients (still present when tiled or floating).

To Reproduce

Install wlroots0.19 dependent compositor (river, dwl, etc). build. run game.

will add momentarily please don't close, need to reinstall a wlroots0.19 compositor and run this.

More Info

No response

No source file or test is named. Start by reproducing the issue with a wlroots0.19-dependent compositor as described, then inspect the attached nvidia-bug-report.log.gz and compare behavior with the proprietary driver. Done means the cause of the fullscreen and mouse-input stutter is identified and a verified fix or narrowly scoped diagnosis is documented.
