I read that there is a feature to save videos using CTRL+SHIFT+ALT+R and I decided to try it:
- I pressed the combination
- Did some silly things to get recorded
- Pressed the combination once more
- I went to check out the webm file created
To my surprise, the video is 0 bytes big. How could this be? Do I have something misconfigured?
EDIT: To be clear, this problem affects only screencasting. Taking screenshots works without a problem.
