Is this a regression or has it always had rendering problems?  Does it render ok with mesa 9.0.x or 8.0.x?  If so, can you bisect?

Only tried it with mesa from git but i can give 9.0 a shot. Though as far as I know the native client is not officially released yet, so I don't know if bisecting will help.

    r600g: re-enable handling of DISCARD_RANGE, improving performance
    
    It seems to work for me now. Even the graphics corruption is gone.
    
    This also boosts performance in Reaction Quake.


Reverting this commit on current master (e721a76) does fix the garbled UI
on my rv770.

I have the garbled issue, but if I try to play the game it soon crashes.  Do you all have this additional issue as well?

Nope, I can play with the garbled issue and it doesn't crash.

Do the piglit transform feedback tests pass?

All 241 tests with this command pass:  piglit-run.py -t transform_feedback /usr/share/piglit/tests/all.tests

I just tried steam and tf2 on linux, and I didn't see any rendering error. The only abnormal thing was this line:
This system DOES NOT support the OpenGL extension GL_ARB_uniform_buffer.

HD6850, OpenGL version string: 3.0 Mesa 9.2-devel (git-b681ed6)

Could you please attach an apitrace file showing the issue?

Apitrace done.. It's about 300MB so I uploaded it to GoogleDrive.

Fixed by Mesa commit aac81387447152b5bda99150414d636a003adc5. Closing.

I can still reproduce the garbled ui on my rv770

Mesa f6b40ddd2d92fd82ccf7ce695d4ed026ef7cfd11
Kernel 3.8.0

the patches in bug 50655 may help.

Does this patch help?

Nope it doesn't help :/

How about this one?

It doesn't help either.

I've tested Mesa f6b40ddd2d92fd82ccf7ce695d4ed026ef7cfd11 
with the patch set "r6xx flushing rework and enable CP DMA (v2)"
from http://lists.freedesktop.org/archives/mesa-dev/2013-February/035081.html
and it doesn't fix the issue.

Note that older kernels (eg 3.5) which don't have CP DMA are affected by this issue too.

I could reproduce the garbled UI on Counter-Strike: Source too.
Reverting 1eedebc65b02130ef7a27062a1ed67972a317a08 fixes the issue on CSS.

Me too.
I have a RV770 and reverting 1eedebc65b02130ef7a27062a1ed67972a317a08 fixes the issue on CSS.

Mesa 9.2-devel (git-4deefd9) showed the problem here with TF2, I don't have CSS.
Added patches:
 r600g: emit a ps partial flush after CP DMA
 r600g: enable CP DMA on r6xx (v3)
and the problem persisted.
Then reverting commit 1eedebc65b02130ef7a27062a1ed67972a317a08 fixed the issue.
Mesa 9.0.3 works.
HD3850 (RV670) AGP, kernel 3.8.0

First comment so I want to thank the devs for their work. :)

Nice to hear from you!

Could you test this patch
http://lists.freedesktop.org/archives/mesa-dev/2013-February/035347.html

It helps here on rv770 and kernel 3.8.0

Patch 3/5 doesn't help for me.  Should I try out the other patches in that series? (nee ATI RV670 [Radeon HD 3870], Git kernel (pre 3.9))

The only patch that's relevant for r6xx is 2/5.  Does that help?  You might need to apply 1/5 first.

> The only patch that's relevant for r6xx is 2/5.  Does that help?

That's just turning that off (same as a revert specific to r600 though).  Works perfectly.

Andreas Boll requested a branch of all my latest Mesa patches for people to test it. It's here:

git://people.freedesktop.org/~mareko/mesa master

This branch fixes the garbled screen and improves the performance (~ 120 - 160%)
here with tf2 and css on my rv770.

Please test it!

Awesome!
With my RV770 all is rendering correctly now in CS:S! Moreover, I'm always at 60FPS (vsync certainly enabled) with all graphical options enabled (even MSAA 2x) (1680*1050)!

Note that I'm using 3.7.9-201.fc18.x86_64.

I tested master Mesa 9.2-devel (git-a40ba43) and TF2 works with my RV670.

Tested and works for me!
