Some high-speed particles lag/freeze the game
Creating a relatively small amount of particles at a high speed completely lags out the game (in 1.16 this doesn't happen).
How to reproduce:
RunĀ
particle smoke ~ ~ ~ 0 0 0 100 20
Which only creates 20 particles, at the speed 100.
Observe the game freezing (only for a few seconds, a higher speed lags it out far more).
