attached screengrab says it all. that's xmatrix running under debrix @ 16bpp (24bpp doesn't do accelerated offscreen pixmaps). the chunks appear to be from a previous X session. workaround: Option "XaaNoOffscreenPixmaps". doesn't happen with 6.7.0-release. need to check HEAD.
it's worse than i thought; offscreen pixmap accel is broken in tdfx too (where both 16 and 24bpp have it accelerated).
and I think you'll find it was broken in nv, too. I'm pretty sure that if you back out this morning's changes to render/{filter,picture}.c and include/picturestr.h, you'll find the root (heh) of all the offscreen pixmap issues. I had an issue where they would almost never display, and those changes fixed it. I had to back out damage and xfixes support while I was at it, however, and didn't get time to drop those back in.
the old debrix tree is dead, this should get handled during the next HEAD import.
Mass reopen. The "LATER" resolution is lame, I'm deleting it. Consider LATER to have arrived.
Debrix is very, very, very dead.
