Comment 13 Orion Poplawski 2015-12-15 13:43:10 EST
Hmm, I can't reproduce.  What desktop environment?  Does it happen every time?  If so, can you collect valgrind output?

dnf install valgrind
valgrind /usr/bin/x2godesktopsharing
Comment 14 Davide Repetto 2015-12-17 10:26:40 EST
In the meantime the customer did a dnf upgrade and this problem apparently went away.

Here is the valgring output, but I think it is now useless:
