Video stutters intermittently
While playing video in Totem, the video will intermittently stutter. I've tried switching from Wayland to Xorg, and also tried muting the audio (--mute) but none of those things make any difference.
It might be unrelated, but if I monitor CPU usage in btop, I notice that there'll be a single core with quite high (70+%) usage, and the high usage will "switch" between cores (i.e. it will go down on one, and then become high on another). If I play the same video(s) in VLC, I don't experience the high CPU usage.
Please let me know if there's any information I haven't provided that would be useful, or if there's anything I could try to figure out the cause of the issue.
