Hello,

I use an Odroid XU4 under Ubuntu 16.04.5 to run KStars (latest release 2.9.8, KDE 5.18.0, Qt 5.5.1). When I launch Kstars from a native display connected to the Linux system, everything works perfectly well (KStars is a beauty on this machine). But when I try to launch KStars through a VNC server, I get the following error (other programs such as PHD2 works perfectly well through VNC):

The X11 connection broke: Unsupported extension used (code 2)
XIO: fatal IO error 22 (Invalid argument) on X server ":1.0"
after 6 requests (6 known processed) with 0 events remaining.
Segmentation fault

The error occurs whatever VNC server I use (TigerVNC, TurboVNC). I tried to use different Window managers (Mate, Xfce4), but it does not change anything, the problem is still here. Going to Ubuntu 18.04 does not solve the problem either. Some googling on the issue did not really help except it might be related to the Qt layer. I am quite frustrated as I really want to be able to use VNC which is quite standard with clients running on many different systems.

Any help on this would be super!

Thanks in advance,
Philippe
