C&C Generals & Zero Hour

Okay, finally I got Generals and Generalsero Hour working on Cedega, but there's a very weird bug, I think it's a mis-translation from DirectX to OpenGL. The problem here is that whenever I go to my base or anywhere that I have units, the screen highlights the screen in my team colour (maybe to remind me which units are mine) and if I take a look at my enemy's base and units, it will highlight their colour instead. This bug is very weird.

OpenGL version: 2.0
Card: NVIDIA GeForce 6600 GT w/ AGP 8x
