This causes worse performance with unnecessary updates of the display. Test Case --------- 1. Set up an Nvidia-only desktop. No other GPUs active. Driver version must be 470 or higher. 2. Add this to /etc/environment: MUTTER_DEBUG_FORCE_EGL_STREAM=1 CLUTTER_PAINT=damage-region 3. Reboot. 4. Log into 'Ubuntu on Wayland'. Observed: The red and blue boxes from the above debugging option follow the mouse cursor. Expected: No red and blue boxes follow the mouse cursor.
