Citrix Workspace/Viewer 2305, which just came out last week, fixes the frequent disconnects / reconnects I was getting on my Ventura M1 machine. I didn't have this problem on my Monterey or Ventura Intel machines.

Oh well, now the brief disconnects are very infrequent, whereas before it was many times a day.
