Insane frame drops and lag spikes since 1.13

There's nothing wrong with my laptop specifications, I run every version before 1.13 with over 80 fps with high graphics and no lag spikes whatsoever.

Yesterday, I've tried playing 1.13 and the experience was horrible. Every time I did something for example : break / place a block, run around, walk around, turn around, enter swimming mode, attack a mob / animal... my game would have a 2-3 second lag spike or a really bad frame drop (to 4-6 frames per second). I've tried playing in windowed, fullscreen and turning down the graphics to lowest and even allocating more ram. But unfortunately, nothing worked.

NOTE : This isn't just me but a plenty other friends of mine.

I have no clue what even could of caused that but whatever it was, it needs to be fixed.
