to reproduce: 1. install xmonad: sudo apt-get install xmonad 2. At the end of your ~/.profile, add the following: export WINDOW_MANAGER="/usr/bin/xmonad" 3. logout 4. login 5. right click on Workspace Switcher select "Preferences" 6. experience rapid flickering ** Changed in: libwnck (Ubuntu) Status: Incomplete => New -- workspace switcher preference window goes wild https://bugs.launchpad.net/bugs/310981 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
