Comment 138 for bug 729979

I think the problem with windows appearing white is different than what you just described. The problem you've identified is definitely worth looking into though. I think its because unity clears the bounding shape of windows when they are minimized.

I've got some code somewhere to make it not do that, now that the relevant bug in compiz that made us to do that is no longer a problem.

Would you be willing to compile and install a custom branch of unity to test?
