Bug 35519

[Problem]
Drop down boxes for menus and context menus show a very brief artifacted box (looks like uninitialized graphics memory), before drawing the correct menu.

Typically it appears when you go to a window that hasn't been accessed in a while and then right click or open the menu.  Subsequent menu activity in that window doesn't show the problem, but if you leave the window for a few minutes and then come back, it'll recur.

Unfortunately the display is so brief it's not possible to get a snapshot.  Hopefully it's clear enough from the description.

It occurs with compositing either on or off, and has been occurring for the past month (I think coinciding with when we switched to r600g as the default in ubuntu).

[Original Description]
When clicking a menu like View in Audacity or clicking a drop down list in Firefox I briefly see artifacts before the list or menu is rendered.
