Most PNG files don't exhibit this, but I have one lying around that has a lot of transparency and does.
/code/env/hardback/lib/python3.6/site-packages/PIL/Image.py:966: UserWarning: Palette images with Transparency expressed in bytes should be converted to RGBA images
'to RGBA images'
The result is wrong colors (green background in a black-only image) and pixelated edges - see attached PNG.
Workaround - don't use one-color PNG images with transparency.
