Subject: x2go on Ubuntu MATE 22.04.3 LTS host & client reorders key presses

[Message part 1 (text/plain, inline)]

Package: x2goclient
Version: 4.1.2.2

Testing against: x2goserver 4.1.0.3 [note: since it's not clear whether the
problem is with the client or the server, I'm reposting the same issue also
for the x2goserver package in case to make sure it doesn't fall through the
cracks].

We're finding that, when typing rapidly on an x2go connection between two
stock Ubuntu MATE 22.04.3 installations with quite up-to-date x2go client &
server packages, the order of keystrokes is quite frequently scrambled
(maybe 1 in 20 to 1 in 100 keystrokes), which makes touch typing an
exercise in frustration.

Obviously there's always the question of whether the bug is perhaps with
the user, although I've been touch-typing for 25 years and the typo rate
(always key swaps) is extremely unusual for me. I also haven't seen that
with the exact same client installation (versions, OS, machine, WiFi)
against another MATE server-side setup (also using x2goserver 4.1.0.3, but
instead MATE 20.04.6 LTS, running on AWS, and in a similar location and
with similar server-side pings) if that's in any way helpful.

The connections are not particularly slow, but on the client side there's
generally a WiFi hop involved. Client-side speedtest.net results: 45Mbps
down / 22Mbps up, ping 21ms up & 204ms down. Server-side speedtest.net
results: 740Mbps down / 925 Mbps up, ping 6ms up and 7ms down.

Christian Kothe
