For whatever reason, I can't open JewTube videos directly in VLC like how I could in MPV.
Only if MPV would work properly on this ancient ThinkPad I wouldn't have the need to use VLC.
But back on i3, MPV spammed my RAM and swap to their max in a matter of seconds and no way to empty them again until I rebooted, and on DWM the same MPV lags (video is far behind on audio), but at least it doesn't eat up all my RAM and swap.
