basically it was working fine for a little bit and rendering the top title
bar at the top of the screen. Then it started rendering it really high up
on the screen far above the top of the screen.

I can't reposition the window and I am specifically trying to create large
dynamic user interaction images so it is a problem for me that the window
appears off screen.

This is out of our control. See the size() reference:

"The maximum width and height is limited by your operating system, and is
usually the width and height of your actual screen. On some machines it may
simply be the number of pixels on your current screen, meaning that a
screen that's 800x600 could support size(1600, 300), since it's the same
number of pixels. This varies widely so you'll have to try different
rendering modes and sizes until you get what you're looking for. If you
need something larger, use createGraphics to create a non-visible drawing
surface."
