--- Comment #3 from sahelanthropus 3dw_50ssu16amyn7@byom.de --- Installing arial indeed fixes this bug. The UI now loads fine, never thought a missing font could make an app this buggy.
There are some bugs only reproducable with cctv hardware like trying to playback video footage (nothing is played), should I create a bug for that? I don't think anyone else has such hardware.
