I've seen this corruption problem when switching workspaces since upgrading to 11.04 from 10.10. It's worst for gnome-terminals, i.e. going from Thunderbird (after reading mail or even just selecting various folders) and then switching to a workspace with at least one gnome-terminal window. Sometimes it redraws the window contents correctly, sometimes it has part or all of the overlaying Thunderbird image in the g-term contents, sometimes just the window border is corrupted, sometimes it flashes the correct window contents then redraws the previous workspace contents, etc.
I have been able to make the problem go away by unchecking the auto- focus feature (System/Preferences/Windows/Select windows when the mouse moves over them). PITA but no more than selecting a blank workspace between each workspace change. What's it going to take to get the importance of this bug set to high and assigned to someone to get it fixed? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/778083 Title: Switching workspaces does not always redraw everything necessary To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/778083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
