Awful Grainy Previews in Library and Develop Slowing Workflow

Question

LRC 12.0 for Mac

Previews in both library and develop modules show as incredibly grainy with ANY amount of grain applied to files. Grain only returns to normal after zooming in 1:1 and grain returns again when making any adjustment, switching modules or viewing other photos. Before and after 1:1 examples attached.

My files are quite large (Fuji GFX100s) and generating 1:1 every time I revisit an image winds up being incredibly time consuming. The only work around I've found is editing without grain and adding as the final step, but then I need to remove it if I want to revisit an edit, which is often. It's proving to be quite frustrating and IMO completely unacceptable. This software has come way too far to be hindered by something as basic as grain. Please fix this soon. It's ruining the experience.

I realized this has been discussed in the past, but I think it needs a bump as it has a big effect on my workflow and I'm sure that of others as well.

The issue is, whenever ANY amount of grain is applied to an image in LRC, the preview renders with EXTREME grain (screenshot before and after zooming 1:1 attached) and cannot be seen normally without zooming into 1:1 and then back out again, which is obviously quite time consuming, especially with files from the GFX100s.

I have had to start applying grain as the final step of my edits, right before export, but if I need to revisit files, then I'm still dealing with the need to zoom 1:1 and back out in order for it to render properly. It's really slowed things down and is making me find LRC to be quite unusable. I see people discussing this back to 2019. Why hasn't anything been done?

I've toggled GPU on and off, does not make a difference.
