I now tested on my Optimus system using PRIME sync with __GL_MaxFramesAllowed unset using mutter/gnome-shell-3.33.2+MR602. The good news is, while previously MR363 had no effect on CPU usage while constantly rendering on this system, MR602 now fixes it. CPU usage on bluetooth-pane circle is ~12%. The bad news, unrelated to this bug is that without setting __GL_MaxFramesAllowed=1 on PRIME sync, mutter is stuttering and intermittently freezing. Let alone still being laggy with or without that setting.
I did not test this so far on the single gpu desktop system since Gnome 3.33 is quite a mess right now with lots of api breakage and increased dependencies. Is it possible to rebase MR602 to Gnome-3.32.x ? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1814125 Title: [nvidia] gnome-shell eats 100% cpu when seconds display is on and screen is locked To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1814125/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
