Comment 23 for bug 1552750

I still see this on Intel 14.04 machine with 4.4.0-64-generic #85~14.04.1-Ubuntu. It happens in fairly random way quite often after close and open of the laptop.

Images may either not display: http://askubuntu.com/questions/850754/what-happened-to-my-dash-icons

or show up with garbling as in attached screenshot.

It may or may not be only the outer fullscreen restore button, as it always is at the moment. It showed in the upper right icon for awhile, it's like something is putting random junk in some random image memory location?
