Cursor movements becomes jerky on shell elements and on preview animations
Affected version
Gnome Shell 42.2 on XOrg (not reproducible on Wayland)
Ubuntu 22.04, Linux 5.15.0-40-generic
Intel® Core™ i7-10850H CPU, NVIDIA Quadro T2000, 32 GiB RAM
Using proprietary nvidia-driver-510 (proprietary).
Bug summary
When moving cursor over shell elements and window elements that are not window contents, the cursor movement become jerky and animations (eg. window overview animations) becomes very low frame rate.
The bug is present only on XOrg (tested on Wayland). I've tested also on older proprietary versions of NVIDIA driver and nouveau - the bug also occurs on Xorg with these drivers.
I think the bug appeared after some update that bring GNOME 42.1 or 42.2.
I currently want to sick with XOrg because of still large number of glitches and limitations of Wayland.
Steps to reproduce
- Start the GNOME
- Open few windows
- Open Preview
- Move mouse cursor over these windows thumbnails
What happened
Cursor movements becomes jerky, frame rate of shell animations becomes very low in comparison to window contents.
What did you expect to happen
I'd expect the cursor movement and frame rate to be the same as inside window contents.
I'd expect smooth animations and cursor movements as in GNOME 42.0 (original version in Ubuntu 22.04 after installation).
Relevant logs, screenshots, screencasts etc.
Sorry, but I think that the screencast and video recorded from phone does not show how smoothness is lost because of low framerate.
