We have a code base that was written and released in 2013, but in iOS 9 the app no longer transitions between SKScenes when the presentScene:transition: message is sent to our SKView.Here's what we tried:Disabling Metal via the Info.plistUsing [SKTransition transitionWithCIFilter:duration:] instead of the predefined animationsTweaking zPositionSwitching to regular UIView animations (this made our SKNodes disappear)None of the above attempts fixed the issue. Note that everything transitions properly in iOS 8Any suggestions on how to locate/fix/workaround the bug?
