Only certain resolutions combined with certain formats seem to work.

The AVI-formats seem to be work less often. Instead, both VP8(WEBM) and H264(MP4) work so far with the resolutions I used. (Thus Preferences -> Screencast -> Record with).

Ah, and do not use Wayland (this records only the cursor movements, otherwise all is black). At the login prompt there is Wayland and "nothing" which I assume to be classical X.
