The Goggles Item renders claim outlines regardless of their position, which means claims 1,000 blocks away are still attempting to display. This can be fixed with a single distance check in WorldRendererMixin.
You can (efficiently) select which claims to render based on the camera frustum with a spatial query on the R-tree, which will not only account for distance but also anything that is out of view.
