Description Michel Dänzer 2007-01-09 03:55:07 UTC
With current git, the xscreensaver hack moebius renders the Moebius ribbon
incorrectly. It looks different with the i915tex and r300 drivers but not
correct with either. I tracked this down to

http://gitweb.freedesktop.org/?p=mesa/mesa.git;a=commit;h=8dcfcad7a2598ba835930aac8f3fd6576e464c1c

with git-bisect.
Comment 1 Roland Scheidegger 2007-01-09 05:48:19 UTC
I've put in a fix which might fix this on r300. However, i915tex must suffer
from another problem.
(also note that some drivers, I'm sure at least for radeon and r200, rely on
current values of _TriangleCaps in their driver state update callbacks, which
will no longer work correctly and needs to be fixed. Neither r300 nor i915tex
seem to be affected though.)

Thanks. The ribbon's grid structure is back with r300, but it's still grey
instead of red. i915tex is unchanged (red but incorrect texturing), as you
suspected.

Mass version move, cvs -> git
Comment 4 Michel Dänzer 2010-01-29 00:34:02 UTC
Works fine now with the r300 driver.
