Description vsergeev 2023-08-27 12:58:31 UTC 
STEPS TO REPRODUCE
1. start any flatpak app like ktrip of plasmatube

OBSERVED RESULT
```
qt.qpa.xcb: could not connect to display 
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.
```
EXPECTED RESULT

App should start

close plasmatube
close weston
start plasmatube as
flatpak run org.kde.plasmatube
or
flatpak run -env=QT_QPA_PLATFORM=xcb org.kde.plasmatube

Probably I forgot to specify some environment:

DE: i3,
Sever: Xorg

This is most likely a distro setup issue or  local configuration issue. I would recommend that you contact your distro or their support resources for help getting it resolved. Thanks!
