@sun @lain What hardware, what kernel, if I get stutter or any issue is driver related I roll back to the previous version and check if it has been reported, usually doesn't hurt to run the old version of something for a while.

I had to do that in an old Mac Mini that ran kernel 6.6 fine but breaks with 6.11, nothing happens if you roll back to a previously working version, that is expected.

See what is happening from Win10 to 11, everybody is complaining lately of slowdowns regressions, etc and there is people reinstalling 10 because they can't work with 11.

That is part and parcel of computing, Linux is no different.
