I could see if I can get a Manjaro boot running and test this myself as I can't reproduce. How did you install appflowy? From source, the releases page, or from the documentation (not the source one.)

I believe Sean installed the package via https://pub.dev/packages/appflowy_editor This is our in-house editor built from the ground up by AppFlowy.
