Pulsing Path Trace Reflection Pass

[griefandgratitude]

Hi there!

Struggling with an issue I am having with what appears to be a pulsing/flickering Reflection pass on my hero light. It's a small light, simulating sun, and it's indirect is acting really strange. I have attached a gif below.

What about Coherent Ratio and Static noise?
