Comment:
~~~@whoizit the issue is that you let Telegram run in X11 env but seem to force GDK to use Wayland, mixing x11 and Wayland in one application can result in incompatibilities. I would recommend to just set `XDG_SESSION_TYPE=wayland` or `QT_QPA_PLATFORM=wayland`~~~
Can you check if not unseting QT_QPA_PLATFORM results in the same back trace.
