I can confirm this with Edgy (upgraded from Dapper), and also Fedora Core 6 (I *think* this was upgraded from FC2, although I'm not 100% certain about that, I didn't do the install).
Could it be related to upgrading as opposed to a fresh install? Perhaps some old config setting somewhere which is causing problems? -- Gnome-panel flashing for kde apps on workspace change https://launchpad.net/bugs/78511 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
