I have installed few apps from flathub but almost all of them exhibit a problem:
- They won’t start sometimes.
- They might if I restart.
Error when I try and run them from a terminal:
> flatpak run com.calibre_ebook.calibre
Invalid MIT-MAGIC-COOKIE-1 keyqt.qpa.xcb: could not connect to display :99.0
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, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.
