Title:
[nvidia] Software cursor in Wayland sessions (EGLStreams)
Status in Mutter:
Fix Released
Status in mutter package in Ubuntu:
Fix Released
Status in mutter source package in Jammy:
Fix Released
Bug description:
Impact
------
In the Wayland session with older Nvidia graphics (usually nvidia driver
470), a software cursor is used instead of a hardware cursor. 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.
