Bug Description

Sometimes when I'm semi-maximizing or restoring a window, I notice the decorations flicker. For a brief moment you see the wrong pixmap/texture down the sides of the window.

See the attached screenshots taken from the attached video at 0:13 and 0:57.

With the new decorations in Ubuntu 14.04 just appeared, the bug has become much worse. Clicking on/off the titlebar of a window shows graphical corruption much of the time.

summary: - window decorations sometimes flicker/corrupt when semi-
- maximizing/restoring a window

Strangely enough, I find the bug to be gone in 14.04.
