Why is my Workspace switcher view skewed

view full story

http://askubuntu.com – I have been using Workspace switcher in Ubuntu just fine but recently have encountered this problem. The windows in the switcher don't fill the screen. I must have pressed some combination of buttons somehow but can't find any information anywhere in regards to resizing them. As you can see in the screen shot it looks like a perspective view or something. I should also add I have a dual monitor setup and nvidia graphics. The switcher still works but the fact the screens don't fit my actual screens is driving me nuts. Thanks in advance for any help. (HowTos)
