I see the same bug since upgrading to 11.04! Here it occurs when I login to "Ubuntu classic without effects", open a panel menu (e.g. the application menu) and wait until a popup text appears. When such popup box closes, it leaves a "hole" in the panel. AFAIK applets are redrawn correctly, only the panel background is affected. It does not matter if the panel background is set to "System default", to "Solid Color" with or without transparency or to "Image".
The hardware here is a HP Compaq 6715b with ATI RS690 (X1200) graphics adapter. @Martin: what is your hardware? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in Ubuntu. https://bugs.launchpad.net/bugs/786115 Title: display glitches in clock and other applets -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
