Question Drifting with Simple Follow with World Up

I stumbled upon a few Cinemachine threads where drifting would occur when no input was applied, especially with a simple follow with world up configuration. This thread https://forum.unity.com/threads/freelook-camera-drifting-in-build-only.975588/#post-7934278 seem to imply that the latest version of CM fixes the issues. However, even using the latest package (2.9.4) I am still getting drifting issues. The only problem is I can't consistently outline the steps needed to reproduce, I just go around and jump and flick my mouse/camera around for a good 5-10 minutes and lift my mouse off the pad...and eventually the camera just keeps spinning around the character. I can then control the camera with the mouse but as soon as I stop supplying input, it will continue to drift. The camera starts off fine and acts as expected so this doesn't seem to be intended behavior; it gradually changes after playing/rotating a bunch (using starter third person controller). Is a "lazy" orbit camera style only possible with World Space?

For reference with the setup up below it usually drifts then stops when it centers on the target after a while.



But I've also used the setup below and it will rotate indefinitely.

 

Sure - the minimal changes I can make to recreate the bug as well: 1) Import starter assets 3rd person, 2) Update CM, 3) Click on player follow camera and change it to Orbital Transposer + Simple Follow with World Up, Aim->HardLookAt, and assign LookAt to PlayerCameraRoot. Then it's a matter of time before it will start to drift after rotating my camera a bunch. The screenshots above were me just trying various ways to fix it. Per the thread I linked above I also had some similar behavior where it would drift when the angle was outside of the -10/10 of 0 and 180 until it reached its target goal.I have some video of the drift as well showing the rig moving with no input but not sure that would help diagnose the issue in any way.


Edit: I also tried removing any changes to the CM Cam in the third person controller just in case it was fighting with it [Comment out CameraRotation()], which still didn't have an effect. It just seems to drift around the 4-5 minute mark of spam rotating my character over and over again while rotating my camera.

 

Sent over a link to your inbox. I also tried testing with the new Cinemachine 2.9.5 (included in the repro project) and the issue is still happening.
