Can't draw to canvas if texture overflows

[Marisa the Magician]

So this is a peculiar bug encountered by someone else, and reported by me.

As it turns out, if a drawn texture goes beyond the area of the canvas itself, it simply does not get drawn.

Here's a test map that showcases the bug. The face should be drawn at all times, moving back and forth, but instead whenever it intersects with either border, it goes entirely invisible.
