Frame rate drop with native.newTextField/Box

I’m not sure if this is the best place for this but I’m noticing up to a 25FPS drop if I add a text field to my game.

So no text field, pretty steady 62 FPS (in sim), add a single text field anywhere then it drops to about 35-40FPS.  Using loq profiler to monitor the FPS.  Over time its caused my system to hang too??!

Just literally adding this single line will cause it:

local emailBox = native.newTextField(100, 100, 180, 15)

Anyone else noticing this?

I started a blank project and sure enough you get a small drop in FPS when adding a field but it seems the more you have going on, the bigger the impact.
