That's interesting. I've never done this but you might want to check
what the clipping region is in your C code. It might also be because the
VM tries to optimize the repaints and it doesn't think anything needs to
be repainted unless you move the mouse over the canvas. Try overriding
update(). Or maybe use the BeginUpdate/EndUpdate functions.

As you can see, I have no idea and I'm just throwing stuff at you. :)
