You are right, it is broken. With spearfish's aspect map you can see the
grid rotation NULLs at the top/bottom which indicates that the layer is not
respecting the canvas bounds. If you set computation region based on
current display (display gui/zoom dropdown menu) and do a full re-render
the bands go away but it is still all-green. Other weirdness requiring
full re-render happens when jumping between normal raster/grid layers
and the green one.
