The video doesn't play in either editor or presentation mode. I only see a black square and when I click the play button nothing happens. Arch Linux wayland, app version 8.3.0.97.

Edit:
The problem exists for MP4 and AVI formats. GIF and MPG work. With any of these 4 formats I encountered an unexpected app crash though.
