Framerate drops very low when using Flex

I'm experiencing very low framerates when loading in a world in a Flex app (with nothing else apart from the OpenspaceWrapper instance and a few buttons). It drops down to 14 fps and below. The same world loaded in an Actionscript app runs at 30 fps.

Any ideas to why?

We never experienced such behavior. Well, the Flex framework is of course "heavier" than using Flash, but no idea why you get such a big difference in framerate. We suggest you to use the Flex profiler to try understanding what is going on.

Ok, found it. Seems this only happens if the parent container is of <mx:Canvas> I changed to <mx:Container> and it runs fine...
