Mozilla Thunderbird 7.0.1 leaves gray areas on the screen when opening and
closing menus. Some are translucent, some are solid gray. The gray areas go
away when the controls they are covering are redrawn. Interestingly, the gray
areas can actually leave the bounds of the window itself, as shown in the
attached screenshot. When I set Wine to emulate a virtual desktop, the problem
goes away.
