(you have a - before 'eglfs', I guess that's a copy&past error?)

I hereby forbid the usage of "hellogl_es2" and in combination with "eglfs"!!;)
It's not working, it's not supported, it's not useful!
It's just plain wrong!!

First thing you should make sure is that you're not using the opengl 
graphicssystem, but rather just a opengl viewport on the QGraphicsView... or 
go directly to scengraph!

I personal recommend qmlscene+Quick2.0 (or qmlview -opengl) to start with.
Alternatively you can alter the AnimatedTiles source-code to set a proper 
QGLWidget as viewport.

IF(!) you still got the same errors, let us know.
