Kasm flooding with kasm_agent error GPU caps helper stderr: amdgpu: os_same_file_description couldn't determine if two DRM fds reference the same file description.

If they do, bad things may happen! Some online posts suggest that it is MESA issue so changed the Workspaces' Graphics Acceleration Method Preference to DRI3 but it had no effect to the flood of error messages. Reinstall didn't really fix the issue. Noticed a message in Kasm Install Settings that said: GPU acceleration is automatically managed by Kasm Workspaces 1.19.0. Configure GPU settings after installation in the admin panel under Infrastructure > Agents. hence the 'Passthru available GPU' should be checked even if there is no available GPU? Still troubleshooting... [quot...
