Incorrect weapon rendering

Hi!

I try to play Serious Sam 3 BFE using Mesa and r600g driver, and I get incorrect rendering of the weapon - it's rendered "diagonal" (see the screenshot).

Linux kernel is Debian's 3.14.4-1.1, but most of the system is i386. Mesa is 10.1.2 from Debian repos.

Card is ATI Mobility Radeon HD 4670.

OpenGL renderer string: Gallium 0.4 on AMD RV730
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.2
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

Is it a known issue?
Comment 1 Vitaliy Filippov 2014-06-13 22:04:14 UTC 
The bug also reproduces on newer mesa 10.1.4 (just updated).
Comment 2 Vitaliy Filippov 2014-06-15 14:21:59 UTC 
Just built 10.2.1 - the bug also reproduces on it.

I've meant "Linux is 3.14.4-1.1 amd64, but most of the system is i386"

Anyone?
Comment 5 Vitaliy Filippov 2014-11-04 22:36:00 UTC 
Linux 3.16.5, Mesa 10.4.0-devel git, the bug still there.
Comment 6 Benjamin Bellec 2014-11-11 18:19:32 UTC 
Can you try with sb disabled, set then envvar "R600_DEBUG=nosb".

OK with R600_DEBUG=nosb

It seems it's OK with nosb (although the frame rate seems lower)

OK, this is maybe related to issue I have :

Yes, "sb" is the enhanced r600g GLSL compiler. So disabling it decrease the performance.
Comment 9 Vitaliy Filippov 2014-11-11 20:36:23 UTC 
Maybe... so the only thing that is left is to get response from someone who can fix it? :)

It's also interesting that the same commit e9822f77a9cc024f528d30382fd5ad21c73a173b is also mentioned in bug 77288...

Absolutely.

The bug does not reproduce anymore with current mesa 11.3
