When we call into external activities (such as In-App-Purchase) that display dialogs, the game pauses and pulsates. It’s like it goes back and forth between the current frame and last frame. Google actually suggested we fix this issue in one of our games and the only work around we found is to make sure nothing is animating before displaying an external dialog. For example, pulling up Google or Amazon achievements using their API will pause the game and show their custom dialog on top of the game. If the user tapped had tapped menu item you’ll see it shake. Anything that was animating on the screen will shake back and forth.
Is there a quick work around for this like drawing the same frame twice before pausing the game? This has been tested to be an issue on all versions of 2.x including 2.2.1 as well.
Thanks for your help! — Todd
