I need to think about it a bit, but according to the spec 0.5px should be rounded off to 1px on retina displays. see https://www.w3.org/TR/CSS2/tables.html#collapsing-borders "Borders are centered on the grid lines between the cells. User agents must find a consistent rule for rounding off in the case of an odd number of discrete units (screen pixels, printer dots)."
