When I upgraded to UE5.0 my character when standing still and the Idle animation running would have some nasty ghosting. I was helped in the forum by changing the VelocityPass from WriteDuringDepthPass to WriteDuringBasePass.
After I upgraded to 5.2 the ghosting came back and it was worse.
After checking all the modified settings in my character blueprint, I discovered that I set Mesh>SkeletalMesh>Advanced>PerBoneMotionBlur=Fasle in UE4 at some point to see if it had better performance.
By setting it back to True fixed the issue for me and I also set the VelocityPass back to WriteDuringDepthPass.
If anybodies Character or SkeletalMesh is ghosting with TSR, check this setting, it may fix it for you too.
