vircadia-native-core Graphics are horribly mangled on AMD GPUs

Vircadia doesn't seem to work correctly on AMD GPUs: vircadia_amd vircadia_amd2 Here are the logs from a system with Windows 10 and Radeon Rx 560 4 GB: vircadia-log_2021-10-12_04.30.51.txt

Wow, that's a mess. Hmm. Unfortunately we're very lacking in people knowledgeable in the details of rendering engines.

Could you set up a new domain with nothing in it and try adding stuff gradually until something breaks? Perhaps we can get some clue as to what is going wrong here.

You can easily clone the Hub and play with it, too.

That's a good idea. Sadly I don't have an AMD GPU to test it on, but I will create an empty domain and test it with a friend who has an AMD card. I suspect it's a vertex shader wrongly compiled by AMD drivers.

Oct 12 '21 13:10 ksuprynowicz

I can give it a test, but I am already 100% sure AMD just broke their driver again. Wouldn't be the first time.. or second.. or third..

Oct 12 '21 13:10 JulianGro

Literally created a label just for these guys

Oct 12 '21 13:10 JulianGro

Maybe we could contact them if we know which part is broken, or make some workaround?

Oct 12 '21 13:10 ksuprynowicz

~~I will give it a test later, but~~ realistically just downgrade your driver. Nevermind, Windows gives me a blue screen.

Oct 12 '21 13:10 JulianGro

Rather an update would be worth trying. The log says that version 21.9.2 30.0.13017.5006 is used, and version 21.10.2 30.0.13025.5005 is available from AMD. https://www.amd.com/en/support/graphics/radeon-500-series/radeon-rx-500-series/radeon-rx-560

Since ksuprynowicz has concerns that this might be a longer standing issue, I will reinstall Windows and check it out.

Oct 12 '21 20:10 JulianGro

Thank you! A friend tried newer drivers but it didn't work either

Oct 12 '21 20:10 ksuprynowicz

So in my testing it works just fine. I tried version 20.10.35.02 27.20.1034.6, version 21.4.1 27.20.21002.112 and version 21.5.2 27.20.20903.8001. (Clearing the shader and ktx cache in between) I cannot easily try a newer version because AMD doesn't support my graphics card anymore..

Please try downgrading to a "recommended" driver version. See: https://data.moto9000.moe/sphinx/PR184/faq.html#amd-downgrade (This page is new. You can provide feedback at https://github.com/vircadia/vircadia-docs-sphinx/pull/184 )

How do I clear shader and KTX cache?

Oct 13 '21 11:10 ksuprynowicz

Oh somehow I missed than when commenting. It should be in %AppData%/../Local/Vircadia/. Just delete the shader folder. I cannot imagine the KTX cache causing that for two people simultaniously but not for me.

Oct 13 '21 11:10 JulianGro

By the way, if downgrading fixes the issue I would be thankful if you can report that back. If it doesn't, I have more broken driver versions to add to the list.

Oct 14 '21 14:10 JulianGro

Sure! As soon as friends test it out I'll let you know

Oct 14 '21 14:10 ksuprynowicz

We just tried 21.10.1 30.0.13025.1000 and it doesn't work. We will try older ones later.

Oct 14 '21 16:10 ksuprynowicz

I confirm that 21.5.2 27.20.21003.8013 works well.

Oct 14 '21 18:10 ksuprynowicz

We just tried 21.10.1 30.0.13025.1000 and it doesn't work. We will try older ones later.

Actually we know that 21.10.1 doesn't work. You posted a log with 21.9.2 that is supposed to have the issue.

Also did someone try reporting the issue to AMD according to their guide? https://www.amd.com/report

Oct 14 '21 20:10 JulianGro

@makitsune I notice you guys have the same issue. Might be good to share any info we have. You can see all the driver versions that have this issue that we know here.

Oct 14 '21 20:10 JulianGro

We need to add 21.8.2 27.20.22025.1006 to ones that have the issue. Graphics are mangled on RX570 with those drivers

Oct 15 '21 06:10 ksuprynowicz

I am also having this issue with driver version 30.0.13025.100 and Adrenalin version 21.10.1 on an RX460.

Nov 13 '21 01:11 CheesecakeCG

Thanks, that is a known broken driver version. Adrenalin 21.5.2 seems to be the newest working version.

Nov 15 '21 20:11 JulianGro

Is it all versions after 21.5.2 that are broken? I think I must've misread the wiki, sorry.

Nov 16 '21 17:11 CheesecakeCG

Current AMD Adrenaline driver is 22.. - is this still an issue with the major update?

Jan 21 '22 10:01 akamicah

I can confirm it is still the issue with the latest 22... AMD driver.

Feb 03 '22 15:02 donataskairys

I believe that forcing OpenGL 4.1 on AMD cards could be worth trying as a stopgap fix for this issue until I get Vulkan version running.

Feb 03 '22 15:02 ksuprynowicz

Hello! Is this still an issue?
