Outline of textures drawn over all meshes in the scene.

I’m having a weird issue in Unity 2021.1.17f1, URP 11.0
Depending on the editor camera angle, a seemingly random texture atlas will be drawn as selection outlines over all selected objects in the scene. If I look along the world X axis, objects are drawn normally.

If I look along negative X, the overlay appears.

If I look down, the overlay changes to a different texture atlas.

The objects in the images have various different shaders, some from shadergraph, some just plain URP/Lit.
Any ideas for fixes / workarounds?

You probably just have Selection Outlined selected? Just uncheck it.
