Transparent backgrounds are being rendered as white

[agustinprod]

Since 15.0, the png / pdf backgrounds are always rendered as background instead of transparent

That's interesting, what version were you on before? I can't think of any code changes that would have impacted that, it must be something within Electron/Chromium itself.

We had to rollback to 10.0.2. Yes, it seems something electron side, maybe they changed some param for pdf printing, or it's just broken, but i'm not sure how to debug it, i tried using 16 / 17 nightlies without success.

If you load this and do a search for transparen you might find some interesting things.
electron/electron@v10.1.3...v15.1.1

Which platform(s) are you running on? Looks like there are some Mac specific behaviors that were added.
