QtQuick app with QBB_USE_OPENGL broken in Blackberry 10.1...

Used to work in 10.0 but something changed in 10.1.


Now with QBB_USE_OPENGL, the screen flashes once at startup (as if the whole screen is flushed before QtQuick components are rendered). Even worse, list scrolling becomes horribly lagged.

 

If I manually set the QtDeclarativeView viewport to a QGLWidget, the startup flash persists but at least lists scroll smoothly. But there is another problem, now the app's tile turns black in the multitask view.

 

I also tried disabling OpenGL alltogether and the startup flash was gone but obviously the UI became too slow....

 

How do I fix the various issues? Any help is appreciated.
