I was on 4.0 but updated a couple days ago with the same issue present. Moving and closing the monitors didn't help either, and unfortunately my display drivers don't have such settings.

EDIT: never mind that, I managed to solve the problem by reducing hardware acceleration (through the Windows interface) to the second-last notch.

I know this is not an optimum solution, so can anyone think of any workarounds to this? Thanks so much for your input.
