It looks like you enabled EGLFS in Qt5. EGLFS need framebuffer version of gpu-
viv-bin-mx6q. If you want to use X11, you have to enable xcb in qt5 (as in 
example in commit log of "07/14 xdriver_xf86-video-imx-viv").

I do not see any simple generic solution to prevent user to choose EGLFS in Qt 
if X11 backend is selected in gpu-viv-bin-mx6q :-(

You will find below configuration I use for X11:
