Light source visible through refraction (IRAY)

Hi,
I know this got fixed with PT (thanks a lot!). Is there any chance for a fix or any ideas for a temporary workaround to make a light invisible with Iray renderer?

thanks in advance and have a great day,

best,
Karol

Yup upvote this , this is crucial for production in interior scenes renders. I also hope that there is more optimization done in the VRAM management on the whole, not everyone have a >24GB VRAM card. In a simple interior room test setup, the VRAM easily hit cap in IRAY on my RTX3080 10GB. This type of typical scene should be manageable on mainstream cards, seeing that other GPU based rendering software like unreal(path tracer), octane etc. can easily rendered this scene without any VRAM issues. Thank you.
