Thanks for the bug report. Next time the slowdown happens, or even before it does, please run this command:
ps -eo pid,rss,cmd --sort -rss > toprss.txt and attach the resulting text file here. It will tell us which processes are using the most memory. ** Tags added: jammy ** Package changed: mutter (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2050866 Title: GNOME Wayland session slows down, mouse skips until the desktop freezes Status in Ubuntu: Incomplete Bug description: I am observing multiple issues with external monitor in a hybrid system (laptop) with Intel GPU and NVIDIA GPU in a Gnome session: - I typically use Firefox with several tabs opened and Visual Studio Code. Some times at least once a day I notice a severe performance degradation. The desktop becomes unresponsive. The mouse cursor skips. GNOME popups up dialogs proposing to close my applications. If I manage to reboot it is all fixed. Sometimes the system locks up completely. This seems like a severe memory leak. I have not noticed it on previous versions. I use the latest updates and drivers of 22.04 LTS. I am not sure how to auto-report this with ubuntu-bug.
