sadly any png or jpeg compression leads to wrong colors for transparent
images in Firefox/Iceweasel. For example the Google logo gets acyan
background. I switched to rle compression which reduced latency but it's
still worse than plain X11.

All pulseaudio sinks seem to be missing when using x2go. I attached tthe
output of "pactl list" from within a x2go session.

That's interesting.  I have noticed a problem in specific circumstances and have not been able to track it down.  I had a limited case where I installed Pyhoca (a fine product - I don't mean to knock it here as this was probably coincidental) and, after going back to the Qt client, all graphics were corrupted.  Somehow, it "fixed" itself.

However, with complete consistency, if I open an RDP session to a Windows desktop and then run X2Go client from the RDP desktop, the graphics are always corrupt.  If I use png instead of jpeg, then the jpegs show fine and vice versa.  The only way to get a usable screen is to turn off compression.  I've not had the time to track down the problem and did not know if it was specific to my environment.  Hence my interest that you are experiencing something similar - John
