@ABeltramo 610 re-introduced multi-GPU problems.

Running an intel iGPU + 5080, I have to set VK_LOADER_DRIVERS_SELECT=nvidia and exclude the Intel iGPU from the box to get the 5080 rendering happily in that situation.

What happens if you don't add that? Can you post the full logs?

@ABeltramo Found the root cause. LXC2Docker didn't exactly pass through things the same as Docker (Undocumented behavior, argh), which caused this. Once I fixed it, it fixed this.
