New Super Mario Bros. 2 3DS Citra retroarch (dirty blue backgrounds)

I know this sounds strange, but a lot of the huge swaths of blue backgrounds have stationary light spots everywhere. I’ve noticed this in any Citra pc build, and any Citra core for retroarch. I have the core running at 3x resolution and it looks fantastic and plays great, but the dirty blue bg’s are driving me crazy, such an eyesore.

Am I the only one that is experiencing this, or is this something to do with Citra itself?

Thanks!

If it’s happening outside of RetroArch, it’s probably something related to Citra itself, yeah.
