So after patching today I've been experiencing some issues.
1) hitting my windows key no longer drops the client to show my desktop. Instead it takes the game UI from fullscreen to windowed maximized.
2) After this occurs my UI seems to have multiple personailities as far as where it says the cursor is and where the game says it is in reality as I can then no longer adjust any of the game settings using the mouse.
3) UI lag when clicking buttons seems worse now also. Turning down graphics settings did nothing to help this for me.
I've tried several different versions of the ATI catalyst drivers. The problem occurs using all of them which leads me to believe it is an issue with the new patch.
