Texture compression (S3TC possibly) broken for Mesa >= 20.0

Since around 2 weeks ago after updating (pacman -Syu), all games (3d and 2d) I try to play (through Steam or just running binaries) have broken textures. They'll be miscolored, offset, just generally glitched and weird. I've tried restarting, updating, installing mesa-git instead of mesa (thought that might be the problem), still nothing has worked.

Anyone have any ideas on how to troubleshoot and fix it?

System Specs:
WM: i3
Kernel: 5.6.3-arch1-1
CPU: AMD Athlon 300U with Radeon Vega Mobile Gfx (4) @ 2.400GHz
GPU: AMD ATI 03:00.0 Picasso
RAM: 6GB / VRAM: 2GB

Mesa version: 20.0.4-1

I've managed to fix it by downgrading mesa to an older version.

Re: Texture compression (S3TC possibly) broken for Mesa >= 20.0

EDIT: that is at best a workaround , not  a solution .

If you want to investigate further :
end-of-edit

post lspci -knn , glxinfo -B , glxinfo32 -B , dmesg and/or journalctl -b .
(glxinfo comes with mesa-demos , glxinfo32 with lib32-mesa-demos )

Do linux native games like xonotic, supertux, supertuxkart also have this problem ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

(A works at time B)  && (time C > time B ) ≠  (A works at time C)

Tracked it down to any mesa version >=20.0.0 (latest that works is 19.3.4-2) is broken for me.

The games I've tried are with native binaries fyi, but haven't checked yet for those games you listed.

glxinfo -B: https://pastie.io/swyzyi.yml
glxinfo32 -B: https://pastie.io/nzbgta.yml

The main thing is that you tested with programs that didn't use steam, proton , wine or other layers but opengl .

The outputs you posted look ok, make sure mesa & lib32-mesa are same versions.

dmesg / journal and xorg log would be next ones to look into.

Okay apologies I got locked out of my forum account. I've tracked down the issue to texture compression (S3TC pretty sure). No idea where to go from here now though.

I've tracked down the issue to texture compression (S3TC pretty sure)

Please share how you arrived at that conclusion (preferably with log output ).

https://gitlab.freedesktop.org/mesa/mesa/-/issues/2908 has many similarities with your issue :
mesa 19.x.y worked, mesa 20.0.1 didn't
The submitter uses a Ryzen 3200 with a Radeon Vega Mobile Gfx .

It does list a workaround, try running

$ AMD_DEBUG=nodmacopyimage program_with_texture_issues

That works! Thank you so much.

I don't have any logs or anything but it's because in Factorio there's an option for texture compression, and the graphics issues were fixed when I turned it off
