Are you using a screen protector? Because Microsoft fixed the fundamental jitter problem all the way back in 2017~ 2018 with the Surface Pro 5/2017 & its Pen + a bunch of firmware updates.
Any significant jitter since is due to either physical interference (ala, a screen protector), low battery life (pen), EMF interference like other nearby wireless &/or magnetic/conductive objects & devices, outdated software (specifically using the ancient + jury rigged to work w/ N-Trig, "WinTab" API), or borked drivers/settings.
The major improvements with the Slim Pen & Slim Pen 2 especially were in terms of EMF shielding, NOT fundamentally improved accuracy in and of itself. If one wasn't having interference problems (and thus notable jitter) before, the latest Pens are AT BEST a minor overall upgrade & w/ some notable new downsides/downgrades to boot!
