Hello,
it looks as ctx->Color.AlphaEnabled isn't set,
at least not in glMaterialfv() (or at all?).
So in VTXFMT Mode, RADEON_CP_VC_FRMT_FPALPHA isnt added to "ind",
and so some programs dont look as good as they do when
NO_VTXFMT=1 is set.
(exaple: arkhart-demo http://arkhart.nekeme.net/en/ or
petroleo.zip, which showed also the vertex-corruption)
Or is it a bug in the program, that it didnt enable GL_ALPHA
explicitly? (If yes: why does it work "right"
in non-vtxfmt-mode and what should be done?)
This (bogus) patch helps when you export FORCE_ALPHA=1
before running arkhart-demo/petroleo.
