On Android (v10, Sony XZ2, AIR SDK 51.1.1.3), I'm encountering similar issues when opening an image with file.openWithDefaultApplication();. runtimeInBackgroundThread is also on.

Sometimes it works without any issue but often I will get a Context Loss (Starling). Also, my observation was that using stage.displayState StageDisplayState.FULL_SCREEN_INTERACTIVE will work way better when returning to the application with no context loss.

When not in fullscreen mode and returning to the application from the image preview (opened by openWithDefaultApplication) I do most of the time have the app then poke out-of-bounds on the top and bottom for ~20 pixels (likely the same pixels in difference as if the app was in fullscreen mode), indicating stage was resized by the opened image preview but not sized back.

@ajwfrost , hello, could you have a lookt at it?,

We need to use 'direct' instead of 'cpu', because it renders faster.

And we can't use runtimeinbackground=false, because App Startup Time increases a lot.

Thanks in advance.
