Holding down PageUp/Down so it get into autorepeat somehow misses some refreshes and the cursor index gets ahead of the view in the window. The grid controls are always ok, but the bitmaps get behind.
I think the multiple on_char events that show up are the problem; the scroll position gets out of sync so what it thinks is the first row isn't updated.
