Setting properties of a UICorner under BubbleChatConfiguration does not update the chat bubble appearance.
This occurs with any UICorner CornerRadius, not just zero.
Reproduction:
System info:
Can confirm! Tried to setup a 9-sliced image as a chat bubble ImageLabel and it’s applying a UICorner radius no matter what settings I apply.
CC @be_nj please take a look 
This seems somewhat related to TextChatService bubble configuration causing display issues on exit transition which we have also been looking into.
i’m still having this issue after roblox is forcing me to use the new textchatservice, i can’t believe roblox expects us to stop using legacy chat service when these simple features don’t work. the old chat service was more customizable as you could actually edit the bubblechat scripts
This is still an issue and causes my image labels (when using slice) to look strange.
This is especially annoying since we’re all forced to use the new TextChatService and these features still wont work.
Hello, thank you all for your patience. Are you still facing this issue? I tried reproducing the bug and this is what UICorner.CornerRadius = (0, 0) looks like on my end.
seems that I still had the same issue
the only way to work around is to set UIcorner instance to bubblechatconfiguration after spawning character for the first time - if we set UIcorner instance prior to this, no effect will be visible to bubble chats
Understood! I’ll continue to investigate the issue. Do you have any additional bubbleChatConfiguration properties set?
Thank you for following up! I had some properties set on my place - but after some tests, seems the current issue still presist if things are in default properties
