[Linux] CinemachineVirtualCamera Component's body's "ScreenY" and "ScreenX" values move towards 1.5 while pressing and moving the mouse



How to reproduce:

# Open the attached project (
# Make sure the “SampleScene“ is open
# Enter Play Mode
# In the Hierarchy select the “VCam“ Game Object
# In the Inspector expand the “CinemachineVirtualCamera“ Component’s “Body“ section
# Observe how “Screen X” and “Screen Y“ values change while doing the proceeding step
# In the Game view left click the mouse and move it in circles for 30 seconds

Expected result: The “Screen Y“ and “Screen X“ values are modified based on where the mouse moves in the Game view

Actual result: The “Screen Y“ and “Screen X“ values go up to 1.5 no matter where the mouse is moved

Reproducible on: Cinemahine 2.5.0, 2.6.17 (2022.3.38f1), 2.8.6 (2021.3.10f1), 2.8.9 (2022.1.16f1), 2.9.0-pre.6 (2022.2.0b8, 2023.1.0a10)

Reproducible with: Ubuntu 20.04

Not reproducible on: Windows 10


# “Screen X” reaches 1.5 slower when compared to “Screen Y“ and sometimes gets stuck at a lower value than 1.5
# If the “Body“ section isn’t opened in the “CinemachineVirtualCamera“ Component the issue doesn’t reproduce
# Changing “Screen X” and “Screen Y” values back to 0.5 allows the process to be repeated again
