I ran the code and I see that the EVT_PAINT handler is incessantly
called when you scroll over and down a bit. I would guess that is
because you have overlapping windows which is not supported by
wxWidgets. Before you can make any headway you have to get it to stop
doing that. Put a print(os.date()) statement in the EVT_PAINT handler
to see what I mean.
I suggest trying to use a single wxWindow to do all the drawing and to
clip the bitmap and lines to only draw the visible portions. You can
even use a wxScrolledWindow if you like to make it more obvious to the
user that they can scroll around.
