Unity3D game heavily lags/freezes after dismissing GameCircle popup
We currently have a Unity3D game in development which should be released on Amazon. Upon updating our Kindle HD to run on Fire OS 4.5.1, noticeable lags (which would also cause the game to freeze from time to time) occurred upon opening and dismissing a GameCircle popup. I'm not 100% sure if Fire OS 4.5.1 caused this but the said issue is not existing prior to the software update.
There shouldn't be much noticeable lag when dismissing or calling up GameCircle popups. I quickly tested a few Unity 3d apps on a few devices, and the most lag I saw was maybe a half second or so when initially calling up the GameCircle popup. Is there any more information you could give about your GameCircle implementation or Unity3D implementation? Knowing the exact model of Kindle device would also be helpful reproducing this issue, as its not one we're aware of at this time.
