It looks like the issue is fixed and was some kind of compatibility problem of the WU with the amd graphics firmware. After upgrading first Linux kernel from buster-backports 5.6 to 5.7 and then firmware-amd-gpu from buster-backports 20190717-2~bpo10+1 to 20200619-1 from testing, the problem vanished.

There are 4-6 commits containing changes or bugfixes for vega20 during those 11 months. Depending on when the Debian package was built, the bits would be similar to the version 20.10 or 20.20 of AMD's Linux driver.
