Hello, i am not sure if I should post there or on bug (for me is not a bug).
But on dark backgrounds, we saw these emojis with white corners:

A user, neutralTTY, reported an issue where Win10 emojis displayed white corners on dark backgrounds. codinghorror asked for clarification on the emoji set being used, and neutralTTY confirmed it was the Win10 style. codinghorror mentioned possibly looking into it on Monday.
Stephen asked for the version of Discourse being used, and neutralTTY replied that it was v2.3.0.beta5. joffreyjaffeux initially couldn’t reproduce the issue but later confirmed it after Stephen pointed out the problem with flag emojis. joffreyjaffeux was able to reproduce the issue and later fixed it with a commit to the Discourse repository (https://github.com/discourse/discourse/commit/d91b47064e0379b5355fd2d9a4f5ada89de7d2a7).

Are these custom emoji or are you referring to an emoji set? Which emoji set are you referring to?
The included emojis. You can choose between Apple, Google, Twitter, Win10 and more styles.
So you set Win10 as styles for emojis. And you use them on dark themes.
Aha maybe you can look monday @j.jaffeux

Indeed, I can repro this, weird. ![]()
