I've got a strange behaviour that happens randomly on my Wind 7 64-bits. Basically at random moments, some stuff that uses the Windows UI starts to get blank or flashing. Below there's an image showing that on Reaper (audio software). But it does happen with lots of other software and especially with Windows open/close or select file dialogs.

I've already tried changing to a non-aero theme, but it didn't worked. I'm running on a Gygabyte NVidea GTX 750 with the latest driver.
I'm out of ideas. I need help on this one.
