EDIT: Seems that adding LD_PRELOAD="" %COMMAND% on steam's launch options fixed my problem. Thanks a lot, everyone :)
I don't know why this happens, I tried playing on windowed, borderless windowed and fullscreen and this bug always happens.

Try disabling the steam overlay I had this issue with doom eternal. Assuming it's on steam and since I believe this is ac syndicate disable there overlay aswell has this problem with division 2
This, and specifically, you can also try disabling steam in game recording for whatever game is giving you trouble. I have found it to nuke performance in some games similar to what you are describing.
By disabling the ac syndicate overlay you mean the ubisoft one?
Yes that one in the launcher settings and as noodlejetski said that command should do the same thing I think
yup, and if that doesn't fix the problem, try adding
LD_PRELOAD=""to the game's launch parametershttps://github.com/ValveSoftware/steam-for-linux/issues/11446
