We are getting around 300 crashes per day while the application is in the background coming from [FBSSceneSnapshotRequestHandle performRequestForScene:]. This is a metal based game. Is there some way I can tell iOS to not try to take a snapshot of the game while in the background? Full callstack below.
Thanks,
