Most of the workstations have AMD Radeon RX 4xx cards in them.  I have updated one of them to the latest driver (version 22.40 released 12/13/2022).  No luck with either VNC (black panel where the graphics should be, but the rest of the interface is normal) or RDP (smeared graphics when the Mechanical window is opened).

I tried adding the Mesa directory to LD_LIBRARY_PATH just before running Ansys, on both a VNC connection and an RDP connection, and the results are the same as above.
