My guess is that AMDGPU may not be set on virtual/opencl... but it is set everywhere else. It used to work great on 1.2 but ever since upgrading to 1.3, I can't see mesa as opencl vendor. Some apps manage to detect it correctly but it remains a hint that something is (at least partially) broken.
I'm not sure by which end to take this. There was a lot of troubleshooting and package re-emerging involved before I decided to create this ticket.
Please advise.
