That's a very common usage scenario for Xpra.

That's a bug in the Ubuntu packages, once again... Don't use those if
you don't have to:

Correct, this works fine in Xpra though, just not in the version
packaged in Ubuntu.

Xpra 4.0 was due to be released this week, but there's one final bug
delaying it.
Until then, you can install it from the beta repository:
