Skylight reflection cut off when High Res Screenshot multiplier is set higher than 1

As you can see from this image


the reflection of the skylight through the window on the floor cuts off. All other reflections seem to calculate fine. It only happen when the High Resolution Screenshot multiplier is higher than 1.

I’ve tried a few things (disabling Temporal Upscaling, increasing reflection capture, increasing skylight HDR size), but the issue persists. Would love some suggestions for other things to try!

Edit: I’m going to try MRQ to see if that fixes it, but at the moment any suggestions on how to fix this issue would be appreciated!

It’s likely Lumen Reflection bug which cuts of reflections after some resolution. It’s fixed in 5.5 (full release, not preview).
