LR 5.3 Win 64-bit: Export from Canon 5D DNG to 6.0 Megapixel JPG results in a file that is NOT 6.0 Megapixels. Instead, it yields a file that is 2912x4368, the native resolution of the camera.

To reproduce, go to Library, click Export..., and in the Image Sizing section check "Resize to Fit:", select Megapixels, check "Don't Enlarge", enter 6.0 in the megapixels box, and leave resolution at 240 pixels per inch. Then click Export. Note the pixel dimensions of the resulting file.

LR 5.3 has a well-known and oft-reported resizing bug where it always outputs the original dimensions if the Don't Enlarge is checked.

It isn't limited to the specific megapixel option you reference.

The workaround is to uncheck Don't Enlarge which runs the risk of enlarging small images.
