Been trying to sort this out now, and I'm kind of halfway through. It seems to be Cinnamon related.
printscreen, gnome-screenshot, vookoscreen... all are producing the “blank” images. But I think I've found a good explaination for that. Went through the Cinnamon issue tracker on Github, where 1 post suggested to first try the panel program: Desktop Capture
. And that one did
So when I was reading through his issues, I found this one: https://github.com/rjanja/desktop-ca...mment-14122904
, explaining why it doesn't work.

It's an ok/nice program so I can use that, even though I'd like to have a “program” (not an applet).
Screenshots are ok, and video to, but I can't seem to make the audio work when recording.
The applet, when using ffmpeg as back-end, is using: ffmpeg -f alsa -ac 2 -i pulse ...
When reading the ffmpeg-wiki::capture alsa
- I guess I have to go with the loop example if I want to record the sound of an audio player?
The line: modprobe snd-aloop pcm_substreams=1
The last part (pcm_str...) looks like it's something that needs to be added to grub, or added to another file if I want it to be persistent?
I haven't used alsa like this before, so I'd really appreciate if someone could give some input.
