I have an M1 Max MBP that was running MacOS Sequoia, and everything was perfect, zero issues. I wiped my Mac and upgraded to Tahoe today, and now I am experiencing lots of jitter here and there and lag all over the place...System Settings, Passwords app, Safari, UI, ejecting apps, copy/paste issues, etc. Safari is fast, but it has already crashed a few times, and that hasn't happened to me in years. I always tell myself I'm gonna wait to upgrade MacOS/iOS/iPadOS, but I always jump the gun and do it quickly. This time I definitely regret it. This is frustrating. I'm gonna wait to upgrade my iPhone just in case.
By the way, I like the features that Tahoe brings, but I really don't like the overall design, not fan.
