UI is incorrectly extending to the left

⏫ Incorrect UI. Upper side extends to the middle, and the chat down below is going all the way to the left. The chat extending incorrectly is particularly frustrating since you cant see what youre typing. Sometimes the room opens to a normal UI size of UI. Refreshing the page does not seem to fix the issue, if its wonky it stays wonky after refresh, if its normal it stays normal (doesnt become wonky) after refresh. ⏬Correct UI  .  This happens on Firefox browser, havent seen it happen when I'm using google chrome. But I really prefer using roll20 on Firefox.

I’ve never seen this in the Firefox Private Browser window I always launch Roll20 games in. So I suggest trying a Private Browsing window too. 

You can also try deleting cache and cookies, then maybe logging out and back in.

Okay after a few more testing here is what I learned: I am only encountering the "UI extending to the left" issue in Firefox. This happens even when using Private Browsing/Incognito. Does not happen at all when using Google Chrome (have yet to test microsoft edge). Clearing Cache manually, and using ctrl+F5 (hard refresh) do not fix the issue if it has already occurred then try to refresh. This issue seems only to happen when opening a "Legacy" campaign room. So its likely an issue with  Legacy WebRTC, as opening a newer Jumpgate campaign room does not ever have the UI issue happen. Interestingly, if I first open a Jumpgate campaign room, then  open a Legacy campaign room, the legacy campaign room the UI extending issue does not occur.

Ah! I always have RTC turned off completely, so that’s why I never see this! I’ll try to replicate with an older Legacy game from 2025.

I've reconfigured one of my old Legacy games to use Legacy WebRTC but I can't replicate what your screenshot shows. The UI bar stays inside the bounds of the Chat sidebar every time I launch the game in Firefox Private Browsing version 147.0.2 (aarch64)
