we've currently experiencing severe performance drops when the iOS-Keyboard is triggered via a GUI.TextField. FPS drops to about 16 FPS. The frame rate is nice, when the Keyboard is never triggered during the lifetime of our application. The performance stays crappy event though the keyboard is "closed".
I've uncommented almost everything but had no luck narrowing down the cause.
Does anybody have an idea what i can try or did anybody have similar problems?
We're on Unity 3.3.0f4 but the problem also occurred with earlier versions. We where able to reproduce this behaviour on iOS 3.2.2 and iOS 4.2.
best regards Benjamin
