This is an enlargement of an image rendered by the 64-bit client (in windowed mode) on my 15in, 2018 MacBook Pro. The white box encapsulates a single pixel of my computer's display. The video appears to have been scaled by 2, probably because the client doesn't support Retina displays. The 32-bit client also scales the video by 2 in windowed mode.
OK, sorry about that, had no idea that was what you meant.

That is definitely not happening for me. Retina should not be an issue. It's just a high res display with a low pixel pitch. As long as the resolution is supported by the GPU and the game there shouldn't be an issue, other than loss of frame rate. Mine has a native resolution of 2880 x 1800. If a 1440 x 900 image is being sent to the display then doubling like that would take place in the display, after the GPU. Any screen shot should be 1440x 900 without any doubling. If the game says it's 2880 x 1800 it's lying or something is happening to it. When I go to the 32bit client with 2880 x 1800 the image I see is much sharper and the screen shots reflect that, using both the game screenshot feature and the Mac screenshot feature. (it's also slow as heck)
