I keep getting vulkan errors too, they're purple and have been occuring since recent patches. I am unable to even get into the main title screen.

What's bad here is that uint 32/32/32 is requested and there's no 96bit format, only 128, so it takes more of an hack to translate this buffer.

Where this confuses me: Is Windows using DX instead of Vulkan and this problem doesn't apply or is this just not supported in Linux drivers?

I'm closing this one, not followed up and the report need more information (like specs, etc ...)
