As mentioned on the CL, is this something that should be fixed / worked around on the service side? It
sounds like a client could cause a GPU process crash (and then maybe worse?)
with this pattern?

Is this specific to particular versions of mesa? Maybe we can blacklist those?
It's fixed in mesa for >=10.6 stable releases.

I'm adding workaround for mesa <=10.5.2 in
Status: Fixed
