[winswitch] xpra slow update

Hello Antoine,

Since version 3.0.4 I find that an emacs window on the remote is very
slow to update edits. I have tried setting xpra > picture > speed >
lowest latency, but that doesn't seem to help. (Should it?) My download
speed is 100 Mbit/s, but the upload speed is only 3 Mbit/s; could that
account for it? I don't know whether the speed has changed recently.

What happens is that I edit characters on a line in a text file in
emacs, and the change often isn't reflected on the screen for several
seconds. It is updated promptly if I move the cursor to an adjacent
line. Otherwise I often assume I've mistyped, and correct it, only to
find that it was correct after all.

Anthony
