Re: [Mesa3d-users] Incorrect Coloring of 3D with Mesa

[rnddim <rn...@gm...>]

That bug sounds about right. But of course, it's unresolved. :(

I suppose what makes me the maddest is that I can't find out where the 
bug occurs. I'm hoping there's a line of code or two I can change in my 
personal copy of Mesa to help counteract the problem, if it's a problem 
with something beyond Mesa (which it seems like it is).

Comparing my gears picture and the one on the Mesa3d homepage (which I'm 
assuming is a snapshot of the correct gears output), this is what 
happens (good output on mesa3d.org, bad output in my original attachment):

Good Output -> Bad Output
Red Gear -> Green Gear (the one that may look cyan or light blue to some 
in the picture)
Green Gear -> Red Gear (may look pink)
Blue Gear -> Alpha (transparent) Gear (it looks like a light gray-blue 
gear, but that's transparency at work)
Alpha (No) Background (appears black) -> Blue Background

Based on this, it's mostly likely that any RGBA color value is read as 
GRAB. I wonder if there's anywhere in the Mesa source code, probably 
where colors are first read, where I could insert an 'easy fix'.
