We are producing a software suite with Adobe AIR (4.5.1 sdk build as 2.6) in FDT 4.5
For our multitouch purposes we build our own classes to perform gestures (scale/rotate) and movement (drag) all at the same time.
Whenever alot multitouch points get added and removed during transformations, everything freezes for a short time (about 1 second). This problem seems to occur whenever 2 object are transformed at the same time with roughly 4-5 fingers, so in total about 8 touchpoints that are used for our transforms.
Because we suspected this issue to be a performance one, we did some short test with just a few Bitmap and Video objects, no userinterface included. The issue stil remained.
To make things even more strange, this issue does not seem to happen when we test it in the browser using flash player 10.2 instead of Adobe AIR.
What could be happening here?
