Easiest repro: change chat version to TextChatService, change ChatWindowConfiguration to have visible textstroke and then send a message with emoji, then change TextStrokeTransparency configuration again and you will notice the difference.
Repro 2.0: make 2 text labels, one with TextStrokeTransparency 0 and second with 1, add any emoji to both and compare.
Workaround: use UIStroke (it won’t work with rich text)
We’ve recently pushed an update to Studio (not in clients yet) that avoids adding extra outlines to emoji that use text stroke. Please give it a try and let me know if the problem is resolved for you.
