Prediction error when I fight certain enemies -> Cancells autofire

Hello.

I have 19 ms to my server and 0% packet loss and playing on a stable 100mbit connection on cable (not wi-fi). In some games recently (the past 3 weeks or so), I sometimes get prediction error which seemingly start flashing when I look at certain enemy players. Prediction error is described as when the server cant predict the position of a player, so I wonder if its my client or the enemy client or some kind incompatibility between our clients. 

Whats even worse and somewhat game breaking for me; sometimes when this happens, my automatic fire gun wont work properly. It will shot a couple bullets and then stop and I have to release the mouse button and press again. I'll link a video when this happened. As soon as the Pathfinder comes around the corner, the prediction error symbol appears. I start to hipfire with my R99 and the gun shoots exactly 5 shots before it stops.

And I just wanna point out that Im 100% sure it isnt my mouse that malfunctions since I logged the mouse input once when this happened and it wasnt that. Also, during this clip am I holding RMB the entire time so its not me who ADSes which makes me stop firing; I ADSes BECAUSE it stops because it made me kinda stressed..

Anyone know the cause for this and how to fix it? Ty in advance.
