Public bug reported:
After some update:
Audio stutters in VLC
Video and audio stutters in Youtube
I think cpu usage might be bigger in VLC too, over 20% vs. below 20%
earlier (one thread gets full 100%?)
Stuttering kernel at the moment is 4.15.0-46-generic.
Kernel version 4.15.0-43-generic definitely worked good.
Cant remember if i could get slight stutter from previous version version -45.
Tried also lowlatency and 4.18 kernel, bad stuttering in those.
(Distro is Lubuntu)
