OTOH, this could be caused by a resource leak that ends up making the 
session sluggish - though other applications would be affected by that 
too, or it could be some kind of miscalculation somewhere.

The first step would normally be to turn most features off to see if 
that makes any difference: no audio, no opengl, clipboard, etc..

It sounds like you have a way of reproducing it so this should not be 
too hard to fix.
Please collect `xpra info` when the session becomes sluggish and once 
when it's not and attach it to a new github issue.

Cheers,
Antoine
