Movie Scene Capture has flickering lens flare / bloom, how do I fix / prevent this?

I’ve been trying to figure out ways to render scenes quicker in UE5.

It seems that Movie Scene Capture is still 5x faster than Movie Render Queue with quality that is acceptable to me.

The issue I’m having is that I get sparkling lens flares (maybe bloom too) that do not appear when using the Movie Render Queue.

It seems as though there is some threshold that MRQ has different than MSC.

How can I prevent these sparkles?
