no it is just a one time hopping to the right, then the Box is fixed again.
When debugging SampleScanner App with the Changes from Jim via XCode i can see that this hopping happens when this line of code is applied in file EAGLView.mm in method (BOOL) presentFramebuffer:
success = [context presentRenderbuffer:GL_RENDERBUFFER];
In addition to that, today i recognized, that in the first case of Scanning the hopping is just small. then when i hit the restart button (not have pressed Done Button) and now hit the Scan Button again, the hopping is a lot more than before. If you do this again, the hopping is small again, than again big and so on…
Here i’ve uploaded the Video Hopping
In the end, now I’m really confused.
