I have a weird problem with my desktop background being corrupt when using full screen mode. I have a dual display setup (27" thunderbolt + 23" HDMI monitors) on a Mac Mini.
I've attached the screenshot. The weird thing is that if I click on the desktop and drag the 'square' the background is fixed behind where I've dragged. It's like it's not refreshing the desktop unless I force it to.
Has anybody seen this before? Is there a simple fix? It's not killing my productivity or anything, but it's rather annoying to have to clear it out manually.
