Hello colleague, i'm not 100% sure, but the grid pattern could be a side effect of rendering to a bitmap. The points in Geom.rectbin are actually filled rectangles (so not accessed as pixels of a bitmap) and with rounding errors might overlap or not depending on the actual coordinate. I'd recommend to file this as Gadfly issue to get further view on that.
