I made a comparator clock on my server, but when its activated, it creates a lot of client lag (fps). Whenever it is not operating, i get a stable 144hz, but when i turn it on, the frame-rate becomes unplayable. This issue does not occur in singleplayer. I've tried moving the circuit somewhere else, but nothing seems to fix it. I assumed it would be fixed by 1.15.2, but clearly, it has not. I've tried this on multiple computers and my friends were also affected. I hope this will be fixed at some point, weather it be in 1.15.3 or 1.16.
