When opening the Lemmy-Web-Settings menu the display-name field contains the username rather than the display-name. After closing this menu it then appears as though the display-name has been changed to the username, which is according to the Lemmy-ui not actually the case.

I've also had issues with the casing. I wanted to change my display name to lowercase but that seems to have very weird results with that menu, apparently ignoring it bit looking as if it took the change until a hard reload.

Edit: specifically the webui now already took my username as lowercase, but summit keeps showing my user as uppercase and its web settings also show it as being entered as uppercase, even though it is set lowercase.

Thanks for reporting this issue. Will look into a fix for the next release.
