I was recently doing some testing of r300 vs. fgrlx for one of
the compiz dev's when I noticed that the reflection plugin no longer (with
mesa from git) works on my x700 even though it worked fine with mesa 7.0.1.
After a little bit of git-bisecting and recompiling xf86-video-ati and
xserver, I managed to locate the commit where it broke:
# bad: [c34b024cf49f3fc06271d561a4069c77d7b65c48] r300: add artificial output
to match fragment program input
Onestone (from #compiz-fusion-dev) says that the shader 'fragment.position'
attribute must be broken.
Fixed in git with commit 113f5b14cbab2d62d5ca470f4b1f82989d3a50fe.
