Hey everyone,
For the past few weeks I've experienced a situation where sometimes when I open mission control or view the desktop there's horizontal black bars/rectangles that appear on the screen. They only disappear if I log out/back in, or restart the computer. Has anyone experienced this before or have any idea what the cause is?
I'm running OS X 10.7.5 on a Late 2011 MacBook Pro

As you can see there are black bars going all across the "grey" mission control area, with a few black square boxes as well.
