I think this bug is very clear already. It really requires someone (most likely future me) to do some profiling on the primary test case:
> just alt-tab-ing between apps would keep the cpu consistently at 100% when hitting it more than 8-9 times per second and *not* letting go of Alt (meaning I stay at the same app). Also, there's a secondary issue you mention: > Also, just whizzing the mouse around on the screen (not moving anything) would keep the cpu at 40-50%. Please remove that from the description because it's a different bug (https://gitlab.gnome.org/GNOME/mutter/issues/283). -- 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/1817620 Title: High cpu usage on alt-tab-ing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1817620/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
