Description Andy Furniss 2011-01-30 04:58:03 UTC 
The bottom square and number in the mesa demo arbocclude are rendering red.

It seems r600c has been doing this for some time, bith swrasts are OK and before this commit r600g got it right also.

Forgot to say this is with d-r-t kernel and git ddx on a rv790.
Comment 2 Alex Deucher 2011-01-31 11:01:39 UTC 
Is this still an issue with the latest mesa from git master?
Comment 3 Andrew Randrianasulu 2011-01-31 11:46:58 UTC 
for me even llvmpipe shows bottom square and corresponding text as red

Using mesa (llvmpipe/r600g) up to commit 7d9e0ea7393c14cbf2d58364726951b14e0d4fc7 (glx: Properly check for a valid fd in dri2CreateScreen().)

Yes it's still the same.

I don't think this is a bug, its just how the demo works, it paints red if the results aren't ready when first asked, which is perfectly within spec from what I can see.

I can reproduce the same result:
with softpipe all squares have the same color
with llvmpipe and r600g the bottom square is red


Should we close this bug as NOTABUG?
