Subpixels in Chrome Android Example URL:

Safari currently returns integer values in pageX, pageY, scrollTop, clientX, etc in safari for iOS (I haven't tested it in safari for macOS), this causes transitions that depend on these properties to look rough, especially the more DPI the device has. Currently chrome for Android already supports subpixiles for pageX, pageY, scrollTop, etc. Example video in Safari iOS:
