In my experience, TextChatService has multiple channels for various in-game features as well as an admin-only chat. The bug for me occurs in Studio as well as in production (on the Windows 11 app downloaded from the Roblox website). One thing to note is that this issue does not occur while testing in Studio with more than one player (as in a locally-hosted client-server game with 2+ players), although it does appear anywhere else.
Whenever the TextChannels are enabled (which is when the player joins), there’s a very noticeable “bar” or UI overflow above the text channels bar which can be seen below:
Here’s a more highlighted version:
Overall, it’s a very minor issue and does not need to be fixed right away, but help would be appreciated. Thanks
