Logic lag

So in-game I get stuttering now and then, but the most annoying thing is when I break a block it sometimes don't register, and after 5 seconds or so I see it breaking. Also happends when hitting mobs, hit don't seem to register, as well as the mobs don't move till after 5 seconds give or take. Now it could be my PC, but as previous version (1.13) I didn't have this issue, I feel it's a game bug. Occurs at random times, both for mob hits and block breaking.
