Whenever I play normally (single player), any version above and including 1.14.4 randomly rotates the view, sometimes for 180°, other times directly downwards. The weirdest thing is that it's random. I've tried it on a multi-monitor setup, one monitor setup, live-boot of Manjaro and the issue is present on all of those. There are no errors in the error log, but it's just unplayable as is.

It looks like "lagg" present on a server with low TPS, but with me having over 300FPS ingame, there's not a lot of reason to believe that low TPS is to blame (client-side).
