I'm running Opera 53.0.2907.68 stable on a Ubuntu 18.04 LTS (x86_64; GNOME) machine.
My problem is...
Every time a watch a video (youtube, facebook, other websites) it plays mostly OK, but at times the image (not the audio) freezes for about 1 second.
This happens many times during the same video.
Not enough to make it unwatchable, but it's definitely annoying.
What can I do to fix this?
Thanks for the help.
