I can see that there is still a bug on Android when returning from the background. If the app is deactivated an then re-activated I get a black screen for a second or two and then it returns to normal. I use render mode auto.
Any ideas? There seems to be a workaround from the starling forum, but it is more than a hack than a bug fix. -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
