After GNOME 3.30 update (even after 3.32 update), I started facingdesktop stuttering.
50% of the time, when I play videos in mpv, the video along with wholedesktop system (screen, windows, menus etc.) starts to stutter. 100% ofthe time, when I stream videos in ungoogled-chromium, he video alongwith whole desktop system (screen, windows, menus etc.) starts tostutter. During stuttering, I also noticed in system monitor, thatprocesses ".gnome-shell-ca", ".gnome-shell-r" and ".gnome-system-m"intermittently hitting 100% CPU.
The above issues does not happen when I log-in as i3-wm session viagdm. They only happen inside gnome session.
Regards,RG.

I forgot to mention how to reproduce the issue.
1) Set up Guix System using a system configuration similar to https://bin.disroot.org/?510c2d858eb869e9#Ef9L5uG3TBiGspwp1X3kebFSoqPWi5XSvzNdisD3V8QY2) Login into gnome-session via gdm.3) Install and open ungoogled-chromium.4) Visit for example https://einthusan.ca(can be accessed only fromCA, so may need a VPN server at CA) --> Movies --> Any Language --> AnyMovie. Play the video.5) You will see desktop stuttering right away or within few minutes.6) Reboot system.7) Login into i3-wm session via gdm.8) Repeat step 3 and 4. You will not encounter desktop stuttering.
Regards,RG.
