What video card and driver are you using? Are you using 32 or 64 bit Ubuntu? Does this happen on all screen edges and with floating panels or only in certain positions? IMaybe the graphics card isn't properly redrawing the part of the screen into which the panel is being placed?
I can't reproduce this problem using Compiz, 32bit Hardy, and fglrx. ** Changed in: gnome-panel (Ubuntu) Status: New => Incomplete -- Gnome panel bugs with secondary monitor https://bugs.launchpad.net/bugs/271343 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
