So first, as I can not mark all versions, this issue started appearing in Minecraft 1.13, and is not fixed until now. I think it requires to be also fixed in older versions as it is major issue for people who experience it. I have not find too many people having this issues so it is possible it is not affecting windows os, or any others. 

To the core of issue. When I first downloaded 1.13 I noticed something weird happening - I was not able to left click, only if I tried like 3 times. Issue usually disappeared after few minutes. Next thing was that (which is not issue) that control settings stopped supporting fn as key. I searched for this issue, but it was soon and I have not find anyone else experiencing same issue back than. When I started playing on 1.15.2 it was still there, but so found quite easy solution - when it occurred I just switched to another window, and back and it worked. Then I noticed another issue, when using new mouse. (I was experiencing all issues also on another mouse and trackpad back than). This issue was with scrolling wheel - on older versions, every "click" when I was turning it meant switch to another slot, but in affected versions it was inconsistent - 2-6 clicks, and while holding left or light button then even more.

This was the time when I started searching for this issue again. I found a video of youtuber experiencing some same things, and some even worse. He had a valuable point - although everything worked fine before, there was some change in hove mc takes input from mouse and kb in 1.13. This is probably the case. About his issues - he also had some strange issue with FPS. It fixed to him to lower polling frequency of mouse, but it still did not fix everything, and I have high end mouse which can not be set to that low polling rate.
This is link to video, it has quite lot of views but does not fix anything to me.

To the last part. I downloaded 1.16 snapshot like a week before to make a video. I set up everything and started but then I noticed something weird. It was like my game was lagging, but it had good fps, when I did not move mouse. I immediately remembered of this old video. I started having same issues. To tell more about issue - when I am moving mouse, normally head of my character (and what I see) should move with it. But now, the mouse was stuck on one point, and it only once per second moved to another one position, it just completely jumped. When using trackpad on my MacBook it was bit better but still not good. I restarted, reinstalled... did not help. Now, when I use my mouse, my characters vision moves once per 10 seconds, although other things in world are moving normally if I am not turning around very slowly my sensor is set at 6400 DPI). I still do not experience it in 1.12.2 or older versions, so I hope there can be some fix done. The game is now completely unplayable for me in newer versions and even newest snapshots are not hinting any fix. Currently I can just hope for fix
