When playing company of heroes occasionally my cursor breaks, it looks very strange and screwy for a minute, then goes back to somewhat normal. The only problem is it looks like it has a piece of it missing and on the left the piece is floating off of the cursor. Also the line when you mouse over text in windows is shown about 1 inch to the right of where it actually is. It presides in windows and games usually until I restart my computer.
I have read many other people having this problem in RTS games, and I think it needs to be adressed.
