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

Well, I tried it with Android (Nexus 7 and Huawai) and iOS 7 (iPad/Phone)
with Qt 5.2 and the option only works on desktops.

But it also does not work on desktops when I set the env manually with


qputenv("QSG_RENDER_TIMING","1");


Cheers,


David
