This should just be a simple pan past little yellow house models, so strobing shadows shouldn't happen. I haven't changed subsurface or IBL or shading rate or anything, can't figure out what would cause these shadow issues.

The only thing I changed between when the pans rendered fine and now, is I added 3D figures (about 3 full cartoon figures, animated poses), and a few props but nothing major. There's about 10 characters and 200 props in the scene, but that isn't unusual. I've cleared shadow maps, restarted the laptop (I know that's irrelevant but you know...), everything
