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..

--- Comment #6 from LukK pablo11_up@yahoo.com --- Bisected with -DTEXTURE_FLOAT_ENABLED. I guess with "ARB_texture_float" every version give me the graphic issue.

--- Comment #8 from gregory.hainaut@gmail.com --- Created attachment 76525 --> https://bugs.freedesktop.org/attachment.cgi?id=76525&action=edit 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.
