I frequently suspend my computer and then bring it back, usually about twice a day.

Lately, when I bring it back, the panel at the top of the screen becomes distorted. Here is a picture.

Logging out will fix the problem, although sometimes it goes away randomly. My launcher was also getting distorted, but it would fix itself as soon as I clicked something.

The functionality is fine, it appears to just be cosmetic. Is there a way I can fix this issue?
