Title:
Activities overview / switching workspaces runs on low framerate
(30fps) on NVIDIA + Wayland
Status in Mutter:
Unknown
Status in gnome-shell package in Ubuntu:
New
Bug description:
(Bug report can also be found on
https://gitlab.gnome.org/GNOME/mutter/-/issues/2247)
Details:
- Ubuntu 22.04 LTS
- GNOME Shell 42.0
- Bug happens on Wayland only
- Dell XPS with i9-9980HK (using the GTX 1650 mobile, since gnome runs very
slow on integrated graphics)
- NVIDIA driver version 510.60.02
- Using internal monitor (4k) + two external 4k monitors
Summary:
The activity overview / the process of switching workspaces runs at half the
normal framerate (30fps) when running NVIDIA on Wayland.
Steps to reproduce:
- Run Wayland and NVIDIA
- Open activity overview or switch workspaces
- Lament the framerate
What I expected to happen:
I expect the overview and workspace switching process to run at the framerate
that matches the monitor refresh rate (60Hz).
