This is an odd one, but no big deal. On this Dell XPS 8930, when I move a Lightroom slider slightly faster than usual, I sometimes get a screen white-out. It's just for a split second, but it's odd. It's like a flash going off on a camera. Have any of you ever seen that?
Is it possible that you are also depressing the ALT key? For some sliders, if you hold down ALT while using the slider you might see all white.
