[BUG] OpenGL games (vivecraft) don't render right through SteamVR with multi GPU setups

[Nathan22211]

Describe the bug
in Vivecraft, or maybe other openGL Vr games. If you have two GPUs, the game doesn't render right in the headset or the vr view

To Reproduce
Steps to reproduce the behavior:

1. Setup: you need two GPUs to reproduce it, both AMD in my case, as well as ALVR on the PC and headset, and a copy of Minecraft.
2. set these enviroment vars in some manner to prevent a complete crash: MESA_VK_DEVICE_SELECT=/dev/dri/renderD129 & VK_DEVICE_SELECT=2
3. ALVR will have you add a launch arg to steamVR, make sure to do that
4. install farbic mod loader + the fabric version of the vivecraft mod into minecraft
5. run steamVR, then launch minecraft. then set the game to VR mode
6. the issue should show in the headset and vr view

Expected behavior
the feed should be normal... or at least not as buggy (ALVR has some minor glitches for me but that's not a SteamVR issue...)

I suspect the radv warning is due to what OpenVR needs and what I have installed. I talked to the dev and we suspect it's a steamVR issue as it's worked with 2 GPUs prior

I can confirm this is SteamVR's doing and not the mod nor my setup. I tried neoforge as well as without all my other mods with SteamVR + ALVR with the same issue, but once I switched to wiVRn + opencomposite, the issue is gone
