info pixel values sometimes taken from neighbor pixel at high zoom levels, but xy coords ok.

For one pixel column, info readout shows pixel values of pixel to the left instead of true ones depending on zoom level, but x coordinate is correct. Setup: Photoshop CC 2015, Macbook Pro 15" with Retina display, PS window on second monitor (27", 1920x1080), eyedropper samples 1 pixel, CMYK image 45 x 33 px is a 1 pixel-per-patch version of the ECI2002 printer test chart, zoom to window (e.g. 2095%). Sometimes, one column (out of the 45) shows wrong values in the info palette: hard to notice, needs mouse-over the entire target. For power of 2 like 1600% zoom, things seem okay. On the retina display, it also seems okay for various zoom levels. The mapping of mouse coords to image pixels seems to be different for the displayed x y values and the actual selected pixels, where some kind of round-off error leads to the wrong position in the pixel image data. Probably new in CC 2015.
