I am experiencing what seems to be the same problem, with gnome-panel freezing and again working after being dragged. I have a nvidia graphics card and the issue happens at least with the 185.xx and 190.xx drivers. A similar problem has sometimes happened with the Firefox window after it is started, requiring the window to be moved for it to start drawing properly.
I have no reliable way of reproducing the problem, but if there are any tests I could do to aid in gathering debug info, I would gladly help. Maybe somebody has an idea of what I could try to do to reproduce it. -- GUI elements stop updating https://bugs.launchpad.net/bugs/342980 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
