Glad this is fixed. I reported (probably) the same bug in this thread: Fedora 41 on the Framework Laptop 16
I cannot reply in that thread anymore (as number of replies seem to be limited to 3 for new users), but I can confirm the problem went away with kernel 6.12.11 in Fedora 41 KDE for me too. Previously I also had to use longterm kernel 6.6 to be able to use my Framework 16.
I’m on arch using kernel 6.13.1 (the default linux package)
The choppiness didn’t go away at all. Perhaps on this stable branch the fix hasn’t been merged yet?
From kernel.org it seems like 6.12 and 6.13 are two different stable branches.
Update: Tried the linux-lts package which has the version 6.12.12. The issue should be fixed on this version, according to comments above, but I still have it 
Now this is out of scope for Linux, but I feel the same issue on Windows 11. Cursor jumps after suddenly moving it, typing (although less but still) feels janky.
The touchpad is not pleasant to use at all.
Update:
You could disable PSR in Windows as well, as noted in this reddit thread.
For that you need to change the DWORD value of DalPSRFeatureEnable in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000 to 0 and reboot your system.
Hey, Fedora just released the 6.12.13 kernel update. The choppiness is not there anymore.
Yeah, and arch also has the 6.12.13 kernel, but for me the choppiness is still there 
Tested with kernel 6.12.14 and the choppiness issue is no longer present.
In fact, scrolling appears smoother than in 6.11.11.
Thanks to @Mario_Limonciello and the AMD team for addressing this.
@Zakhar_Voloshchuk @Almindor Fedora has a separate package named “amd-gpu-firmware”. Its version on F40 is currently “20241210”.
Perhaps the corresponding package on Arch Linux also needs to be updated? (I’m not familiar with Arch, so the firmware may be packaged under a different name, or as part of another package).
It’s possible the choppiness issue was due to an interaction between the firmware and kernel drivers.
Solved my issue using dGPU 7700s on FW16. Kernel 6.12.16-cachyos on Gentoo.
Thank you everyone!
