Well, let's be clear: if the settings are to set the filtering to "Quality" there still should be no seams, even if that is not the ideal setting.

What do you have your minimum shading rate set to in your render settings?

The other thing is if something accidentally got changed in the shading rate on your figure Properties tab (even if you render at 0.20 min shading rate in render settings, it's not going to render better than what is set on the element's properties tab).
