Comment 11 Orion Poplawski 2020-01-14 03:46:52 UTC 
I think this is the relevant x2go bug report: https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1376

And this seems relevant to the X11 code: https://gitlab.freedesktop.org/xorg/xserver/issues/283

In any case, this is going to need to be resolved upstream.
Comment 12 Ulrich Sibiller 2020-01-14 06:36:33 UTC 
nx-libs has a workaround for that bug included in 3.5.99.21 and newer.

The relevant nx-libs issue is this: https://github.com/ArcticaProject/nx-libs/issues/808
