I have experience with this and have seen the same behavior as you. A window's size and position are restricted to integral points. If you pass a non-integral rect, it will be expanded outward to be integral. I suspect that this is for the situation where a system has a combination of Retina and non-Retina displays. You don't want dragging a window from one to the other to change its size. If your window is borderless, you can make it transparent and have a fractional-size view (subview of the contentView) do the base opaque drawing, thereby effectively setting the size of the window.
