The server is not TigerVNC, so we need to determine if the issue is with TigerVNC or TightVNC.

Do you see the issue with other clients?

The server is not TigerVNC:

But had not noticed issues using other clients.

TigerVNC doesn't even want to connect to it's own server:

Could you try using TightVNCs client for a while and see if the issue appears there as well?

Will try to do that.
