Xpra: Ticket #2352: xpra shadow server has unexplained delays

When connecting to a shadow server, I experience significant delays in drawing. In one case, tray icon was "stuck" in 1 clipboard request pending (maybe somehow related to #2338 ?)

In both cases, graph looked like this:

The "bump" in the graph indicates me doing "something" in the shadow server (in that case, I switched workspaces). Before doing "the action", the server was "idle" (I was working on something in the client) After doing "the action", it seems that server "stops" sending data.

Please advise on what diagnostics would be helpful :/

Client: Win10 / Xpra-Python3-x86_64_3.0-r23016 Server: Ubuntu 16.04.6 / v3.0-r23052

Does the problem go away if you disable the clipboard? Does re-connecting help?

Please advise on what diagnostics would be helpful :/

As per wiki/ReportingBugs, the usual would be a good start:
