Recently, it’s no longer possible to change Quality Level or Edit Quality Level in Studio via the settings menu. When I change the value in the dropdown field, the field resets to what it was immediately after I stop focusing on it, and it no longer live-updates in the viewport behind the settings menu. You also seem to sometimes get completely stuck on automatic if you attempt to set it to automatic.
This value can still be properly changed via the command bar and the viewport will update, but the settings menu does not display the updated value until Studio is restarted.
