Also try running the application with "-platform xcb" to explicitly 
select the xcb platform plugin. "-qpa xcb" when configuring simply 
selects xcb as the default platform.

Might be useful to do "export QT_DEBUG_PLUGINS=1" if a plugin fails to load.

The eglfs (as in egl fullscreen) platform plugin is not meant to run as 
an X11 client.
