[X2Go-Dev] Bug#1369: Bug#1369: Bug#1369: Keys do not release when using Emacs in X2GO Client

[Yan Zhang]

Hi Uli,

I found a temporary solution. If I disable the transient mark mode, under
which the selected region is highlighted, this issue goes away. So I guess
the issue is related to events generated by rendering the highlighted
region. And one thing I forgot to mention is that if I start emacs without
GUI (i.e., emacs -nw), I do not have this issue.

On the other hand, I have tried to use ADSL/ISDN, change my emacs version
to both 26.1 and 24.3.1, and upgrade NX to the nightly build. None of these
has any effect.

Thanks and regards,
Yan
