all windows opening behind active ones

view story

http://ubuntuforums.org – I run Ubuntu 12.04. All my windows have started opening behind whatever current one I have open. (This includes launching a new program, right-clicking to open in new window, etc.) I tried the solution listed at this and this post but it did not change anything. I don't know why it would start doing this, because I have not made any customizations recently. I do update my system whenever I can, so it may have started happening after an update. What should I do? (Hardware)
