During the NWWC 2020, Extazz and I, we both coudn't play ont the german servers because we had this bug. From the inside, the "shaking" is not seen. The only thing you feel is a big lag, like if you had 200 ping, but the game says you have 20.
I don't know if he used a hack or not, but I can confirm I had the same bug without using any hack. And this only happened to me on the german servers (Extazz aswell).
