Does mesa 9.0 work ok? Can you bisect? Please attach your xorg log and dmesg
output.

No mesa 9.0 don't work,also I tried mesa 8.0.4 with "--texture-float" and give
me the same bad rendering. 
OK, I can test but i have my times..

Bisected with -DTEXTURE_FLOAT_ENABLED.
I guess with "ARB_texture_float" every version give me the graphic issue.

texture good

Hello Alex,

I'm a developper of PCSX2 and made some tests on my side. I think I understand
the cause of the bad rendering. 

At the beginning of the program we upload a float texure (see attachment). I
ask Lukk to dump the texture with glGetTexImage (see attachment). If you
compare both textures, we will see that some floats were rounded.
I upload Lukk's texture and I can confirm you that we got same rendering issue. 

The upload of the texture is fine on my HD5770 with mesa 8.0.5. So the issue
feel chip specific.

Cheers.
