There is a large amount of aliasing on ray traced reflections. The reflections look as expected until you zoom in on the sphere (press Z or C to zoom in/out). The reflections become very noticeably aliased. This can be clearly observed, even without zooming, when applying a normal map
Found in 4.22 CL# 5660361 and 4.23 CL# 5807975
Lots of aliasing on all objects showing in the reflection
A much smoother reflection with minimal aliasing
