Luis, My continuing experience with framerate drops and high CPU is that they usually turn out to be two different bugs. If the CPU spike occurs when you drag a window under the dock then that might be bug 1743976, which occurs when things change under or very near the dock.
Ideally let's keep this bug about just the framerate drop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730460 Title: Framerate drops when moving windows across physical displays To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1730460/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
