I blame that on the DBUS initialisation since it was faster before. I'd wait for more Qt releases first

That's the most annoying thing actually, and the #1 reason I added debug output. Result: it's not on our side of code where we lose time (logic analyzer is still below 10ms, for example). Once I know how to profile Qt apps properly on the device I'll find the issues, I think. My gut feeling tells me it is still the SVG hack we had to employ, but without solid test data this means nothing.

As far as animations go: if 1-2 concurrent animations slow down a QGraphicsView then something's wrong with the frameworks
