Gray screen when connecting to remote server

[frenzybiscuit]

When using the .deb package. I get a gray screen when trying to connect to my remote server.

The app does launch with the deb package, unlike snap and flatpak on Ubuntu 26.04.

I can confirm this for the local connection and for a remote connection. Both are running in Web Browser Firefox.

@frenzybiscuit could you confirm the issue has been addressed with the latest release?

Yes I can confirm this with with v.0.0.18

Since 0.19 I get a lighter grey screen than before - but still grey:

It works if I launch it using this command in terminal: open-webui --no-sandbox

However I can't use that as a workaround because SSO login opens in a new browser window and doesn't pass the session back.

Tested on: Ubuntu 26.04
Version 0.20.

I can confirm that with option --no-sandbox it is working otherwise not. (v.0.0.20)
When I start without the option i get in terminal..

Same for me on Arch Linux with v.0.0.20 as AppImage.
