Every minute or two, the game will freeze for about a second, every second, about three or four times. After that, game in fine for the next minute or two. Is it autosaving?
Also, the longer I play, there will be a mouse delay, which grows more and more noticeable. Gradually grows more noticeable until it's at a point of unplayability. Delay becomes unplayable at a around 5 hours of gametime. Only closing the game and relaunching will remove the delay. Refreshing chunks, textures, and shaders doesn't remove the delay, only closing and relaunching does.
Playing Vintage Story through Arch Linux, downloaded through the AUR. Less of a bug and looks more like an issue.
