Comment 144 for bug 753144

I don't know if this is helpful/relevant/already mentioned, but this problem exists in KDE too. The only difference is that the windows are black instead of white. It happens in Kubuntu 11.04 and after a fresh install of 11.10 it still occurs.

In Kubuntu the fix is easy and immediate. In System Setting -> Desktop Effects -> Advanced untick the "Enable Direct Rendering" option. My onboard Nvidia 'GeForce 6150SE nForce 430' works flawlessly (all effects, like blur, and no more empty windows) after that. I wanted to use Unity, but there is no equivalent option in CCSM as far as I know, and searching the Ubuntu Wiki/Google yielded confusing, mixed results.

I am assuming the Kubuntu issue is the same as the Ubuntu issue since the problem is exactly the same - I have used both and the behavior is identical. So is it possible to disable direct rendering in Unity for us poor folk with older computers who do not have the option of upgrading or am I making a mistake in my logic?
