Floating Cesium Tiles Seen Floating in Sky in Path Traced Reflections

Has anyone found the solution to why all of a sudden we see the messed up half loaded CESIUM tiles floating in the sky in the reflective surfaces when using path traced rendering? It is making the renderings unusable currently and is a very distracting visual bug.

I haven’t used path traced rendering much, so it’s not something I’ve seen. But it would help if you a) showed us what you mean, and b) defined “all of a sudden”. That is, in what version did it start being a problem?
