Before & after pasting clipboard

SUMMARY
- Copying and Pasting an image that has transparency into another app pastes it very distorted. 
- The alpha is preserved, and the image dimensions are the same as original, but the opaque pixels look like they down-res to ~40x40 px and up-res back to original when it's saved in the clipboard.
*see attachment.

STEPS TO REPRODUCE
1. Create image with 1 layer that has transparency.
2. Select all, Copy.
3. Open any raster image app (MS Paint), Paste.
