Public bug reported:

Binary package hint: compiz

When switching focus from one window to another, the target window may
become blank. See the attached screenshot, where I opened two gnome-
terminals and clicked on their titlebars alternately - the issue was
triggered after about 5-10 clicks. I've had this happen on other
appications too, e.g. software-centre, empathy, etc.

Doing shade+unshade, maximizing or clicking away from the problematic
window usually makes the window contents come back. The window remains
responsive to both keyboard and mouse (by the way, in the screenshot the
mouse cursor was an I-beam before I pressed PrtScr).

This is on up-to-date natty, installed from scratch using the daily
image from the 1st of March.
