Window color remains white (windows 7)

Hey guys.

A little issue here. The window color remains white, whatever i do. I've rebooted. Can't find any thread on it. Looks like every other "item" colors are correctly updated. What could have gone wrong ? D:

I've checked in the registry, and window color isn't set to white, yet it is.

I did the

UseMachineCheck, and set its value to 0.

Blur, and set its value to 0.

Animations, and set its value to 0.

thingy. And now the backgroung textures work.

But still, it's white

Thanks
