Why is there no transparent background when in puzzles?

I just checked it, and if you use the default lichess background, (https:////lichess1.org/assets/images/background/landscape.jpg) puzzles are transparent, but if you use a custom background, the background is black.

Looks like certain pages block the reference to the domain outside of lichess (explaining the behavior mentioned in #11):

do you know of any reason for this @ProgramFOX ?

I do not, but I opened an issue on our issue tracker: github.com/ornicar/lila/issues/8844

Okay, it's a known issue - computer analysis functionality conflicts with custom backgrounds, for technical reasons: github.com/ornicar/lila/issues/6684

ah, thank you!
