This is on mobile (chrome) of the current beta2.

GitMate.io thinks possibly related issues are #3959 (New app menu makes external links very hard to use), #5021 (3dots-menu to small for long app-names), #6267 (theme app does not change logo nor background), #455 (App menu should be white with dark icons to fit style), and #217 (Theming app: preview for log in background image).

@jancborchardt I thought we already fixed this? :'(

[rullzer]

@skjnldsv maybe you did after beta2?
