I suspect the xcb problem could be related to the setuid call in
mythfrontend/main.cpp.  I would suggest increasing the log output to
maximum first.  If no other log output occurs then I would try removing
the setuid call.

The eglfs problem looks like a Qt/EGL problem when creating the main
window - confirmed by your pi3d test.  I have no experience of Ubuntu
Mate with RPi so I would minimise the unknowns and test with Raspbian
first.  If that is still problematic then I would suspect the Qt build.
In that case I would suggest using the Qt5 libs and plugins from my
archive - just point LD_LIBRARY_PATH and QT_PLUGIN_PATH to the relevant
places.
