Bug#1527: native X11 fonts stop being rendered as the desktop is shared; functionality is restored on unsharing.
Package: x2goserver Version: 4.1.0.3-4 (amd64, devuan Beowulf)
Running, let's say "xfd -fn fixed" or any other sofware whose GUI is based on native X11 fonts (mwm) from within a remote x2go session (DISPLAY=:50), strings are rendered correctly until a second connection to such display (via the "x2go/x11 Desktop Sharing" facility) is established on the same :50 display, even with the same user.
As soon as the connection is established, X11 fonts rendering stops for both the clients and all X11 clients which rely on such feature (e.g. mwm, or xfd) are shown with blank text boxes; applications which rely on different font technologies (e.g. the sakura terminal) are not affected.
As soon the second connection is closed, font rendering is restored for the initial client, and writings reappear on the next window refresh.
Such behavior is consistently reproduced at every attempt.
Both client connections are originated from the same Centos 8 machine, with x2goclient 4.1.2.2 and disabled "set display DPI setting" option.
Sincerely

What is the version of the nxagent package?

I am sorry, I cannot seem to trigger this behaviour. Please post a step by step instruction including all the software you are running. For me this is working fine like this:
- start and x2go desktop session with application /usr/bin/xterm
- in the session run mwm &
- in the session run xfd -fn fixed
- connect to that session with a x2go shadow session (from a different client)

nxagent declares version 3.5.99.22 I reproduce the problem with the same steps, if I got them correctly the other two commands.
- I run a session with xterm as "custom desktop", from which I exec
- the "shadow session" is a "X2go/X11 desktop sharing" session on the same display, with the same user. Nvidia drivers+VirtualGL are probably the only strange thing installed, but I'm not sure how could they interfere.
