[maemo-developers] Horrible performance of GL rendering; why? (Qt, N900)

Hi!
   I'm experiencing a horrible performance of the QGraphics 
"accelerated" rendering when using the attached test program.

The program uses QGLWidget as a viewport when any command line parameter 
is passed, and normal Qt rendering (software only?) otherwise.

When I run the application in my N900, it seems that the software 
rendering is much smoother than the GL one.

Am I doing something wrong? I would expect much better performances, 
with such a simple test application.


Any help is much appreciated (I'm trying to port Mappero to Qt :-) ).

Ciao,
   Alberto
