It looks like it is still running in eglfs mode. Did you set the
appropriate parameter (QT_QPA_something?) for xcb? Even under X, it will
run in eglfs mode if the parameter is not set, and may not work well
because eglfs is conflicting with X for painting the screen.

One think to bear in mind, if you keep switching between QT and eglfs on
the same machine, bad things may happen. For example, under appearance,
you should select QT when using xcbs, and select OpenGL when using eglfs.
