After upgrading mesa to 21.0.0-1 login into remote xrdp session no longer works.
Downgrading to 20.3.4-3 resolves the issue.

I tried to debug this here
but apparently the permission denied error is not relevant since it also
appears in the logs for a working session.

Local sessions still work without any issue.

Steps to reproduce:

- Upgrade mesa to 21.0.0-1
- Log in remotely using xrdp
- Black screen appears with only the cursor
This task depends upon

Same xrdp problem here.

Logging in with ssh reveals further issues that are probably related to 70015,70151.
Downgrading to 20.3.4-3 resolves the issues.
