Weird graphic distorting or something next to the plane

I normally dont fly in external view a lot. But i got some weird distortion graphs next to the plane…
Anyone any idea what is and more important, how to lose it?

DLSS does that to water. Use TAA instead and you won’t see it anymore.

yeah… i didnt see for some reason al my settings changed for no reason. Graphics and control settings were just changed and gone?
