Apple also avoids the issue by always working with integer scale in software. For a fractional scale, it is downscaled by hardware. They also do not have exact percentage scale (for example: their 175% is actually 177.7778%, because it better allocates the pixels, i.e. use 8 pixel block on the display for each 9 pixels in framebuffer).
