Holosights ghosting with frame gen

The red dot on the holosight ghosts (not smears) with framegen. (Collimator, Open Collimator, Holographic)

This doesn't seem to happen with scopes though (GP 37, PSO, PAO, RNBW etc)

Any thoughts as to why?
And to any reason why they couldn't have the holo sights work like the scopes?

I use FSR, but I hear it happens with DLSS FG too. (Feel free to clarify)
Not sure if there is any difference between 40/50 series or DLSS4.

If you have the issue or any additional information you can report it to GSC:
