Yes, this issue started after I upgraded my ubuntu from 16.04 to 18.04. I
didn't experience it with 16.04.
I also have a newly installed 18.04 on a very same notebook and that one is
also affected.
For the record: the youtube videos' lag issue was fixed weeks ago. I
just mentioned it, because I had a feeling that that was a similar bug.
I installed the '4.17.0-041700-generic' kernel. It fixed the problem partially:
- Cheese still stuck sometimes (very very rare), but continues in less than a
second without interaction
- I cannot reproduce the issue with VLC and hangouts any more
- Super Tux Cart still affected (it might be a different issue?)
What should I do? Cheese works much better with the mainline kernel, but
it still stops sometimes for a moment.

Title:
video lag
Status in linux package in Ubuntu:
Confirmed
Bug description:
The problem exists for months and I didn't find a good answer on it.
It affects many softwares: Cheese, Super Tux Cart, VLC (when I rewind
the video the sounds continues, but the video stops), youtube,
Hangouts and every software where video is played.
I experienced that there are 2 things that can break it:
- if I move the mouse out and in on the affected window (it doesn't work in
full screen)
- if I open the system monitor, the problem also disappears
