Broken AUG scope
In windows, when you're aiming with AUG the screen around the scope is blurred. On Mesa we have strange black pattern. The pattern changes on each cs:go restart.
I can reproduce it on Mesa 17.1-git + llvm 5.0 + RX480 and on stock Ubuntu 16.04.2 (Mesa 13.0, I believe) + R7 240
Note: green rectangles are not the bug, it's me hiding my steam name.
Thanks for reporting this.
It would be nice if you can upload good/bad screenshots. And it would be very nice if you can record an apitrace which reproduces the issue.
I can't reproduce this with my Fury, and have never seen it, for reference...
Any tweaks like R600_DEBUG etc?
I have the same problem on my RX 480 and current mesa git.
I produced an apitrace but it is ~734MiB and trimming seems to be corrupting it, I might be doing something wrong.
How should I share and eventually trim/extract only the relevant part from the trace?
You can upload the trace on Google Drive or some similar storage service.
I took another apitrace, which I uploaded here : http://dl.free.fr/u43NDpptG
But when I replay my traces (glretrace), I notice :
- Graphical corruptions when I open the ingame console or when a map is loaded (which is NOT a problem I seen during normal runtime). The menu is fine.
- The scope bug (this report subject) is not visible from the replayed trace on my end...
Maybe it is an apitrace bug from my side? Not sure if I may report this to the apitrace project, this happens in apitrace from git too.
Try setting the environment variable MESA_EXTENSION_OVERRIDE=-GL_ARB_buffer_storage when capturing the apitrace.
Thank you very much Michel, indeed masking this extension produces a correct trace that can be replayed to reproduce the scope bug.
So here is a new apitrace showing the bug : http://dl.free.fr/oD7tgoSw9
For reference, the outside of the scope is supposed to be slightly blurred. Random screenshot found on google images to show the expected rendering : http://misc.team-aaa.com/perso_skullgun/MaJCSGO/Augscope.jpg
Thanks for the trace.
The issue can be reproduced with mesa/llvm from today on RX480. I'm investigating.

bo clear hack, needs 4.9 kernel at least
This seems to be the same problem as with DOOM Vulkan, some buffer is not cleared when it should be. It still needs to be investigated wether it's game's fault or radeonsi's though...
Thank you Samuel.
Grazvydas, thanks for the patch, it does fix the visual issue, even though I understand this is not a proper fix. I did not notice a performance drop (in CS:GO at least) with it, so I will be using until this issue is resolved.
There is no corruption on scope with current mesa git + llvm 6.0 on TAHITI. I don't have RX480 anymore, so I can't test it with POLARIS.
The apitrace link not longer works so can't test on POLARIS but assuming this is fixed as per comment 11. Please reopen if this is not the case.

issue on 18.1.3
Unfortunately this is not resolved on RX480 and mesa 18.1.3.
I attached a screenshot of the issue.

I confirm this is happening on mesa-git + RX560. Unfortunately, the hardware is not mine, so I cannot test it with bo clear hack. There is also some texture corruption ob de_nuke, but i'm not sure if it's related to this bug: https://i.imgur.com/tjfI2uY.jpg. If someone can test these with bo clear hack please do it, I can't do it myself as I'm still waiting for the refund money for my dead RX480 :(
Here is the apitrace for the scope bug : http://xaapyks.info/csgo_linux64.3.trace.bz2 (mesa 18.1.3)
md5 = a876e4fd64168486c3e6dfefd9edca86
It seems I have to set STEAM_RUNTIME=0 to reproduce it.

I am not experiencing this.
Still happens with Mesa git master 9fc1ce258cf956d21a9d4940a3c10c5547d93408, Polaris10 only, Oland and Tahiti are not affected.
Is this bug still being worked on?
The problem is still here, but there's a little update: sometimes texture gets cleared correctly.
Currently running Mesa git master 31e4c9ce400341df9b0136419b3b3c73b8c9eb7e
If you run steam from the command line with:
Does that fix the issue for you?

Yes, it does fix scope rendering for me.
Is any negative performance impact to be expected with that flag? Also, is it doing effectively same thing as patch from comment #9?

Potentially but it's unlikely to be noticeable.
