The PPA mentioned in comment #190 doesn't try to remove Unity anymore and is functional for Raring. I installed the updated packages from this PPA but unfortunately it didn't reslove the bug.
I've noticed that the blank windows are only a problem for windowed programs. If I minimize maximized program and follow the procedure to reproduce the bug I don't get blank white window. If I do the same for windowed program it results in blank white window.
