It possibly is the Unico theme engine. I've set up two alternatives on my computers: A modified "Greybird" theme (from the Shimmer project) that uses no external GTK+3 theme engine and a modified "Adwaita" theme, using the Adwaita theme engine. Both these themes have bugs, too. But they do not flicker and are reproducable. No stray random stuff.
(If I had not found these working alternatives, I would have had to ditch Unity sooner or later.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/981084 Title: Menu labels tremble/jitter as their height and placement changes on mouse-over To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/981084/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
