Public bug reported: Dear all! Starting from some beta 18.10 i experience continious segv fault in Wayland session. COnfiguration is acer swift 5 with 2 additional 24" dell monitors. I choose wayland session in gdm. Everything starts smoothly and good, gnome applications runs ver good. If i will not use any qt application - everything is good. If i start any qt - graphical server crashes immediately and drops me to gdm prompt. During usual xorg session everything is OK.
