Application doesn't crash if the outlying session is started as Gnome + X.org.
(In reply to Mauri Sahlberg from comment #3) > How do I run it under X instead? The "How to Test" section of the Wayland Change page has some details as to how to switch between the two: https://fedoraproject.org/wiki/Changes/WaylandByDefault#How_To_Test
