Hi Daniel. I can't even reproduce it in 18.04 anymore. I tried: - Booting 18.04.2 from a usb disk - The 18.04 GNOME Wayland session (what I'm trying now to avoid a bunch of other bugs) - The 18.04 default Ubuntu Xorg session
all of them seem to be showing reasonable <1% gnome-shell CPU usage when showing just a gnome-terminal running top. Don't know what fixed it but it does seem fixed. I can live boot 18.10 if that's useful or even 19.04 if there are images for that already somewhere. -- 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/1773959 Title: High CPU usage by gnome-shell when only running gnome-terminal Status in gnome-shell package in Ubuntu: Incomplete Bug description: Even when doing nothing but displaying a terminal screen with top running gnome-shell uses 10% of a CPU. That seems excessive. I disabled all extensions to try and make the test fair. Enabling the system monitor extension increases the load to 13-14%. It seems that the gnome-shell screen painting is highly CPU consuming even if screen updates are infrequent (1 a second for all these cases).
