Empty Project with vuforia only
Default ARcamera prefab in scene
Basic unity input field
Android build (tested on note4, galaxy s6 and galaxy s7)
Every time you click on the input field and the keyboard pops up, vuforia camera will lag more and more until its unusable. (3-4 keyboard pops)
It is possible that it has something to do with the OnApplicationFocus method of unity that stacks up lags on vuforia camera only (unity keeps running smoothly).
It seems that the method OnApplicationPause releases the pressure and the camera doesn't lag after it's called
Profilers won't show any performance issues.
P.S, the same lags happen when I try to use NativeToolkit to bring up native popups of messages from android or anything else thats native.
I need a solution
