I'm not quite sure, but it seems to me that there is at least one change (but allow me to test): If I'm now panning from left to right (move the mouse to the right), then the screen is stable. If I move it to the left, I get the flicker. Which is pretty strange. Unless I'm completely mistaken, the tiled mode created flicker no matter whether I scrolled left to right or right to left, it just depended on the position. Wierd.
