I am using Java 15 and running on Fabric 1.16.5 and experience this issue.

How I'm Reproducing this Issue:

IMPORTANT: Make sure CameraOverhaul's setting "Enable the mod's effects" are set to "Yes". This issue will not occur when this variable is set to "No".
1.) When pressing F5, when I switch from the 1st-3rd person to the 2nd-3rd person view, it will cause the camera to shake.
2.) When pressing F5, when I switch from the 2nd-3rd person to the 1st person view, it will cause the camera to shake.

List of mods I'm using:

This is a similar issue with #11 and is a general incompatibility with mods.

I am going to close this issue. While not the same case, the generality of #11 covers this issue.
