Hi, I don't know if this is going to help, but I was experience a similar problem in Popos 20.04. In my case, the misbehaving app turned out to be Mega from mega.nz which I use for cloud sync.
Their ubuntu 20.04 deb package causes noticeable stuttering. After disabling the app the desktop becomes smooth again. After enabling it again the computer becomes fast and smooth. This problem did not exist in 19.10 using mega's deb for 19.10. The stuttering happens across the board, in every activity randomly. Thanks. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1872796 Title: gnome-shell animations are noticeably stuttery when the Ubuntu extensions are enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1872796/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
