A reboot of the app actually fixes the issue...

Actually switching dark to light recreates the bug 🤦🏼‍♂️

Yeah I saw this PR and tested it during development. But apparently the app is running just slow enough in debug mode such that this issue is not appearing during development. I think adding a short delay before changing the theme of the app will fix this (hopefully).
