I guess these are the two things darktable needs to do on a high-pixel-density display:
- scale up the icon and UI pixels by a factor of 2 - reduce downsampling of photos by a factor of 2 (e.g. if a 4K photo will be downsampled as 1K on an ordinary screen, we can display it on a retina screen as 2K) Is my understanding of the problem correct?
