Short description of error
Screen space reflection smudges when the instance object has a different orientation than the original
Exact steps for others to reproduce the error
Rotate the view to see the smudged reflection happening. It looks like the effect accumulates.
Hit Alt + R to clear the rotation of the plane, the reflection will look ok.
