I found that in some software, e.g. gnome-sushi, cheese, etc. video stream is malfunctioning.
Due to this bug, the output of video is shown as a simple green screen, but the audio is fine.
Here you can check the gnome-sushi bug I submitted earlier: https://bugs.launchpad.net/ubuntu/+source/gnome-sushi/+bug/1512316
I attached a screenshot and some files dumped by apport from cheese, to this issue.
