There is one more change I did after upgrading from 19.04 to 19.10. This is a KVM VM - and for some reason, the GUI (X) sometimes freezes after the VM is paused/saved/resumed, while SSH still works (this was also before 19.10 and behaviour did not improve in 19.10).
I've changed to Wayland to see if it this kind of freezing happens there as well (so far, it doesn't). High CPU usage on all cores happens with Wayland only. I've just checked, it doesn't happen with regular X; CPU usage is normal/low there. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1850874 Title: gnome-shell (via Mesa/LLVMpipe in a virtual machine) uses all CPU cores just to update the screen Status in gnome-shell package in Ubuntu: Triaged Status in mesa package in Ubuntu: Triaged Status in mutter package in Ubuntu: New Bug description: This started to happen with Ubuntu 19.10.
