[Interest] Performance of Qt 5.2 much slower than Qt 5.1?

I have tested Qt 5.1 and 5.2 beta 1 on my Nexus 7 with the flying icons
benchmark (
https://github.com/qtproject/playground-scenegraph/tree/master/benchmarks/flyingicons
)
and the performance of Qt 5.2 is worse than 5.1 although it should be
better or at least similar according to
blog.qt.digia.com/blog/2013/09/02/new-scene-graph-renderer/.

Does anyone know what could be the problem? Can anyone reproduce this
performance problem?

I have also created own tests where the same results occur –

Cheers,

David
