I think it's graphics card issues but I wondered if anyone has found a way to solve it.
I'll move around in the viewport or my cursor will move over objects and the viewport will be set to shaded but will go back and forth between that and wireframe, randomly, except when I'm not doing anything. As you can imagine, makes it hard to work. Seems like a draw problem. I've changed the display from open gl to direct 3d but same thing happens. And I believe everything's updated.
I'm using max 8 and a Radeon 1600 card.
