Hi,
I was running sz81, a ZX81 emulator using SDL, remotely with an IRC client and noticed, that while it worked nicely if started in a session using an x2go Linux client, after disconnecting the session and reconnecting using a Windows client, the application window came up garbled with display artifacts.
What's more, if I disconnect and reconnect the session using a Linux client, it somehow manages to blank my complete local display as soon as the SDL application window gets focus. This confused the hell out of me, and I first suspected a crash, until I figured out what was going on. It's really an SDL issue, I verified by running parallax-4.tar.gz from http://olofson.net/examples.html which displayed the same behaviour.
I would guess x2go has some kind of SDL passthrough mode which is somewhat buggy and doesn't work with windows. Is that correct, or what is the expected behaviour?
