Do you have specific steps to reproduce this problem?
Is it a regression?
Is this using MS Windows as client perhaps?

This sort of thing is quite hard to debug, you may want to run the
server with `xpra start -d mouse` then you can look for button events in
the log as `xtest_fake_button`.
Button 1 is the left, 3 is right. (True for pressed, False for unpressed)

If that doesn't clear things up, please create a ticket with
reproducible steps. I should be able to fix that.
My guess is that we don't get the button release event for some reason
(maybe sent to another window when we don't have focus).
