On 11.10 this seems to be the only workaround to fix the bug: "I disabled Compositing in 'Window manager Tweaks' and it blew right through. Of course that has other repercussions). So I tested further and I find that the key is 'Display shadows under popup windows'. So either it's not playing nice with gksudo's UI takeover, or gksudo isn't."
