Another workaround is to change the current theme (via system/preferences/appearance) to another one. Once done, the panel get drawn correctly and you can switch back to the old one. This approach has the advantage that it can be used also where the panel is locked down (as in UNE edition).
As a side note, if you have to switch off in a hurry and are not able to use any of the workarounds proposed here, I think it is safe to hit the power button: it should be linked via acpi messages to the shutdown dialog. -- Visual corruption affecting several panel applets https://bugs.launchpad.net/bugs/439448 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
