Hey Terry, So the reason why the tearing is a lot slower in 06/09 patch is because the canvas is using the turtle.ScrolledCanvas widget. Everytime the window resizes, it is calling a callback to `onResize` -> `adjustScrolls` to update the scrollbars. When I comment out that binding in turtle.py (line 358) it still tears, but it snaps back a lot quicker. The main widget is already a 2x2 grid (ScrolledCanvas). I tried just returning the ScrolledCanvas, but that didn't work either. I will try to ask in stackoverflow tomorrow and seeing what they say!
