It might be a upstream Mesa issue, I opened an issue on Mesa 2 weeks ago : https://gitlab.freedesktop.org/mesa/mesa/-/issues/9767

They seem to say it might be a CS2 issue. ¯\_(ツ)_/¯

Here's a video of the issue.

Interesting. On mesa 23.1.7 and an 7900XTX (RDNA 3) the smoke itself is rendered properly, though it has blue edges:

Same with

OpenGL ES profile version string: OpenGL ES 3.2 Mesa 23.0.4-0ubuntu1~22.04.1
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20

Using an AMD Radeon 6750XT

Same thing happening here, took a few screenshots. I have a RX 6700 XT and I'm running CS2 on Arch.

Same issue here, the smokes are invisible other than some visual glitches, for me it shows up as red lines on surface edges, but other than that it might as well not be there at all.

The screen-space effect when you're inside smokes also has some visual glitches, but it does block vision. Got strange edge-effects again there and everything turned blue in certain positions.

The mollies and nades also looked off, but not as noticeably, here's the molly:

Guess mesa will become THE competitive CS2 standard for the time being...

[iSaluki]

I am able to reproduce a very similar issue on my AMD Radeon RX 6600 XT.

[LiamDawe]

On my 6800xt, Mesa 23.1.8 smokes mostly work fine but sometimes I see the weird blue and yellow outlines:

[MacTavishAO]

AMDVLK seems to work better and gives higher fps but shader stutters are as high as 5-6 seconds.

[Calinou]

This seems to only affect AMD GPUs (possibly Intel?). I can't reproduce this on NVIDIA 535.104.05.

Window is smoked here

[alou-S]

Interesting. On mesa 23.1.7 and an 7900XTX (RDNA 3) the smoke itself is rendered properly, though it has blue edges: !

Yes its a issue that's on the recent releases of mesa. I have done a in depth bisection of the issue on the mesa issue pointing which exact commit versions cause which smoke render bugs. Most of the bugs seem to be directly related to GPL since disabling it fixes the issue.

BUT THIS ISN'T A FIX THAT YOU SHOULD BE USING. Disabling GPL will hugely tank performance and cause stutters.

[MacTavishAO]

Window is smoked here

I'd like to ask the following question:

I personally won't play the game at this state because it's not fair to other players and myself, but will Valve ban players for see-through smokes whilst it's them releasing the game in this state?

@kisak-valve What should players do?

[alou-S]

You may get banned if you abuse it. If you really really want to play the game without abusing this bug you have the following options:

1. The full smoke render bug only happens in the latest 23.2 branch and doesn't occur in older versions. You could simply downgrade to the older version by your own distro's methods. There are other minor bugs in the older versions tho but not gamebreaking.

2. To fix the minor bugs RADV_DEBUG=nogpl envar can be used which will disable GPL and hugely effect performance by causing stutters during shader compilation. It will basically be pre GPL experience.

3. Use the AMDVLK Driver which will both have terrible performance and stuttering issues due to its inferior shader compiler and lack of GPL. Honestly option 1 is better.

Yeah option 2 and 3 are terrible so you can stick to option 1.

[MacTavishAO]

2. RADV_DEBUG=nogpl envar which will disable GPL and hugely effect performance by causing stutters during shader compilation. It will basically be pre GPL experience.

I've already tested it with nogpl and this is the result.

[alou-S]

2. RADV_DEBUG=nogpl envar which will disable GPL and hugely effect performance by causing stutters during shader compilation. It will basically be pre GPL experience.

Oh my bad then it was probably an error. It probably fixes the minor issues on the older versions I will edit the comment.

Replying to #3258 (comment)

Oh, not exactly your fault. nogpl still renders something compared to default options as you see on the screenshot.

[alou-S]

Okay yeah updated the reply to reflect reality

[Zipdox2]

There's not even a trace of smoke, but you can see the grenade on the ground. If I walk into it my screen does go gray.

I was able to launch the game on my Steam Deck in desktop mode. Smoke bug is reproducable there too. SteamOS 3.5.

For those interested:
Launching the steam directly from ~/.local/share/Steam/steam.sh allows you to play CS2 on the deck.

[Zipdox2]

Valve releases game after not testing it on Linux
Sound doesn't work on Linux
Graphical glitches on Linux
Smokes don't render on Linux
Doesn't work on their own hardware

🤣

I was able to get a video capture of the exact bug with my Steam Deck. Sorry for low quality, I was streaming the game to my desktop using Remote Play.

Update:

• CS2 had two bugs with smokes, one of which has shipped and one of which will ship today with smoke rendering. We believe this will fix the smokes if you are using mesa 23.1.8.
• As identified in this bug (https://gitlab.freedesktop.org/mesa/mesa/-/issues/9767), starting at commit https://gitlab.freedesktop.org/mesa/mesa/-/commit/859e059aa912dee5a7ef36e21eac00e6f5fcc7b3 smokes don't render at all on the mesa 23.2 branch. We are working with the RADV folks to root cause.

So hopefully by a bit later today if you use mesa before 23.2 (i.e. before commit mentioned above) we believe smokes will be correct. Hopefully we'll be able to get a RADV fix and/or workaround on 23.2 shortly.

[danginsburg]

Another update: I've got a workaround for the bug on 23.2 so hopefully when this next update ships smokes will work on that driver too.

thanks, do you happen to know if updates for Linux get included here or do we just guess when the update has been release? https://www.counter-strike.net/news/updates

[MacTavishAO]

From latest update patchnotes:

Fixed smokes not rendering correctly on AMD GPUs on Linux

oh nice they include linux changes in it

[MacTavishAO]

I can confirm smokes work as expected with mesa-git for me. I'm keeping it open so other linux players can chime in.
Thank you @danginsburg!

On a side note, I'm getting 40-50% of FPS I get on windows or using windows build with dxvk. Is there any word on that?

[vaxerski]

No clue then :/

Ontopic, I can attest to @MacTavishAO, this is fixed for me. Molotovs as well.

[JacKeTUs]

Smokes now fixed with mesa 23.2.0

[alou-S]

Smokes, Molotovs and AWP tracers seem to be rendering fine on Mesa Git

[mackal]

Appears to be fixed here as well.

[ghost]

The smoke bug is fixed.

This is kindof related. But, on "world smoke" I suppose. There is rendering anomalies/errors aswell.
You may need to open the video big to see it. But it is very noticeable in person.

Smoke and molotov are fixed, but now the presence of molotov produces this screen graphics corruption, on mesa 23.3.0-devel (git-d7f3fdc262) with RX 6700.

[FuzzyQuils]

Replying to #3258 (comment)

I don't see the bug here?
If you mean the black regions in the smoke, those are actually shadows being cast through the volume.

EDIT: nvm I see the light bleed at the edges. That is weird.

[hp-pepster]

Replying to #3258 (comment)

Same here, current mesa-git (23.3.0_devel.178368.80a1896539b.d41d8cd-1) AND release (23.1.8) but with Radeon RX 6950 XT. Even happens with a smoke only.

[KeironO]

It has been fixed on my end.

I'm having the same issues, even on High.

First, thanks all for the great repro information and follows ups. Glad to hear the original issue is fixed. Regarding this:

I'm having the same issues, even on High.

I'm going to close out this issue because the other issue being talked about here is the same as #3287. I believe I have a fix for that one, which will be in the next update.

Tested with the new update, smoke still produces this :

@kisak-valve should we open a new issue regarding that bug? I have run some more tests.

[kisak-valve]

Hello @hp-pepster, yes, follow up issues should be reported separately so that they can be tracked properly.
