iOS Issues

After some limited success with getting my app on iOS, I have hit a roadblock.  At first, I was publishing my app and it was working great.  All of a sudden after fixing some issues, it no longer works.  I reverted back the changes but no success.  It works in desktop and on Android just great.  Here is what I am seeing

works (kind of)

- If I use low res iphone size it works (but looks terrible)

- If I use high res iphone or ipad with CPU, it also works but looks terrible and is poor performance (also the native extension alert does not work)

doesn't work

- If GPU is on, there are just some wierd shapes on the screen (but mostly black)

What doesnt work was actually at one point working great with great performance (including the native extension).  The remote debugging shows no errors.  Hopefully this is something someone has seen and an easy fix but it is driving me crazy.
