Screen Problem after waking up from hibernate

I find that sometimes, when I wake up from hibernate, I get something lik

I don't really know how to describe it but, notice that the rendering is not sharp with all the lines etc

I feel like this is a glitch with Windows 7 Ultimate 64, Sometimes when exiting games this happens, hit cntrl-alt-del and then exit out of that and tell me what happens.

the glitch is still there ...
