Hunch turned out to be incorrect but not too far from the truth: There's a hard-coded repaint region for the grid that's just too small at high zoom levels unless close to the origin. (That explains why I occasionally found a place where I saw half the screen full of grid.)

I'll try fixing guide lines not being rendered while dragged at these high zoom levels, too, while I'm at it.
