How to reproduce:
1. Open the attached “IN-90312_BugReport_Cinemachine” project
2. Open “SampleScene”
3. Locate and select the Virtual Camera GameObject in the Hierarchy
4. Enter Play mode
5. Observe the Virtual Camera Transform coordinates in the Inspector window as well as the Camera position in the Game window
Expected result: Virtual Camera stays in a fixed position
Actual result: Virtual Camera drifts to the side
Reproducible with: 2.8.9(2021.3.37f1), 2.10.3(2021.3.47f1, 2022.3.54f1, 6000.0.31f1, 6000.1.0a8), 3.1.2(2022.3.54f1, 6000.0.31f1, 6000.1.0a8)
Reproducible on: macOS 15.1.1 (M1 Max), Windows 11 (by user)
Not reproducible on: No other environments tested
Notes:
- The effect is most noticeable when GameObject Transform coordinates are set to far away: (X:100, Z:100)
- Setting Dead Zone Width to 0 prevents the Virtual Camera from drifting
