I installed xorg 7 on a fresh install (no existing xorg). Everything went smoothly except for one show-stopper problem: When I move windows vertically, their contents get corrupted (redrawn improperly). If I just move it horizontally along the top of the screen, it works fine. As soon as I move it a few pixels vertically too, slices of the window get redrawn in wrong places. Specifically, slices seem to be redrawn progressively lower than where they shouldn't be. This is under both ati/radeon and vesa drivers, so it's something higher level. Tweaking driver options gives nothing. I tried changing resolutions and bit depth, switching window managers, changing DPI... no luck.
My hardware is Radeon 9000, all driver options are defaults. The compiler is GCC 4.0.2.
This also happens when scrolling (in programs which optimize scrolling, like konqueror, firefox).
I tracked down the problem to the "-fweb" optimization flag in gcc when compiling the xorg-server package. Corruption only occurs with "-fweb".
Thanks for tracking it down, not our bug then.
