# Introduction close #9965 When landing on twenty you should be able to see a white screen flickering if you had setup dark mode. This is because before the SPA has been loaded we're not displaying anything, which in a white screen from the browser. During this period we should display a background color following the user's device theme. ## Reproduction In order to reproduce this behavior define a fast 4G connection from your network console. ## Cons Device mode might not the one chosen afterwards when the user has been authenticated => We should store appearance settings in the local storage in order to optimistically render the default "loading" background ( wouldn't be 100% bullet proof for instance if the user is now unauth for some reason ) Body background will be override by theme after app bootstrap
