Air 3.0 rendering problem

I just packaged up an android game using Air 3.0 and the captive runtime (very excited about that!)

Much to my surprise I now have a few new rendering bugs.

(GPU mode / full screen, Android 2.3 Motorola droidX)

Graphics are intermittently missing, then will appear later than they were added.

I have a movieClip which is "tiled" with an image pattern from the library. This "pattern" movieClip is the only one which is randomly failing to appear, also the seams where the image repeats are now slightly off/overlapping a bit.

when i minimize the app... if i open it back up later, it might start to open, then just drop back the the apps menu... basically it crashed. When i open it next the game is starting from scratch when it should have been in a paused state.

this is all intermittent and only happens in 3.0 (except the slightly overlapping image tiling made w the paint bucket tool, thats constant)

I'm going to do some more testing with this...

Has anyone else noticed any differences in rendering/performance specific to gpu rendering?
