Did. Still flickers. 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.
Greetings,
Thomas
