Priority: medium Bug ID: 74784 Assignee: dri-devel@lists.freedesktop.org Summary: Strange artifacts when rendering tees in Dota 2 Severity: normal Classification: Unclassified OS: Linux (All) Reporter: brunojimen@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa

Created attachment 93753 --> https://bugs.freedesktop.org/attachment.cgi?id=93753&action=edit Strange artifacts in trees

Hi,

When playing Dota 2, randomly and depending on the ligh and the perspective, some random artifacts appear in trees. They also appear in other places, but the trees are the most visible ones.

My graphics card is an AMD HD5470M (AMD Cedar) and I am using Arch linux 64 bits and mesa compiled from git at commit 356aff3.

I thought this problem could be related to this other bug report: https://bugs.freedesktop.org/show_bug.cgi?id=72895 but applying that patch doesn't help.

The attached screenshot shows the problem with the trees.

If you need anything else, just ask.

--- Comment #1 from Alex Deucher agd5f@yahoo.com --- Please attach your xorg log and dmesg output. Are using using the llvm backend in r600g? If so, does disabling it help? Also, if this is a regression, can you bisect?

--- Comment #2 from Bruno Jiménez brunojimen@gmail.com --- Yes, I am using the llvm backend (you mean the --enable-r600-llvm-compiler configure option, don't you? )

I will compile a mesa package without that option, and tonight I will see if it continues to happend and I will attach the xorg and dmesg logs.

And yes, it is a regression, although the best date I can give as not happening is the 29th of December.

If disabling the llvm backend doesn't help, I will start bisecting.

Thanks for all!

--- Comment #5 from Alex Deucher agd5f@yahoo.com --- This may be a duplicate of bug 68451. Make sure your kernel has this patch:

drm/radeon: skip colorbuffer checking if COLOR_INFO.FORMAT is set to INVALID

--- Comment #6 from Bruno Jiménez brunojimen@gmail.com --- No, Arch doesn't seem to apply that patch. But I am still using kernel 3.12.9, should it be there too?

Also, that bug report was reopened on the 19 Dec, but I think (I may be wrong) I recompiled mesa after that and didn't see anything wrong.

And compiling without --enable-r600-llvm-compiler doesn't help either.

If I can help with anything else, just ask.

Thanks

--- Comment #7 from Bruno Jiménez brunojimen@gmail.com --- With mesa at commit 6d1cecb (Friday evening) this problem is fixed.

Thanks!

P.D: Maybe it was related to the hyperz problem of r600g drivers, as I am using a revision that is after this commit http://cgit.freedesktop.org/mesa/mesa/commit/?id=01e637114914453451becc0dc8a...

Could you set the following environment variable to re-enable hyperz?

R600_DEBUG=hyperz

--- Comment #9 from Bruno Jiménez brunojimen@gmail.com --- With 'R600_DEBUG=hyperz' the problem happens again, so I'm afraid that it's something related to the hyperz.

If I can help with anything else, just ask.

--- Comment #10 from Alexandre Demers alexandre.f.demers@gmail.com --- The bug is not fixed, HyperZ has only been disabled by default. Please, keep opened to track the problem until HyperZ is fixed.

--- Comment #12 from Bruno Jiménez brunojimen@gmail.com --- Hi,

I have just tried with 'R600_DEBUG=hyperz' to enable hyperz with mesa built from yesterday master.

I have played a match with a hero that used to cause failures with some of his abilities, but as far as I can tell, there has been no problem.

So it seems that this bug has been resolved (^_^)

If you need anything else just ask.

Thanks!
