Weird color artifacts in Raytraced view when orbiting?

Hi,

I’ve noticed that in Raytraced view, when panning and orbiting the scene, weird color patterns pop up.
What I’ve done is populate the scene with a few boxes and simply switched to Raytraced view. I haven’t changed the render settings in any way.

It seems to have a penchant for Germany. :sweat_smile:
