All types of reflections have an uncommon bug

[Serg_Karmach]

I decided to make a mirror. But I have noticed, that all mirrors in my UE5 are bugged. If I make a new project, the issue remains. If I use lumen, screenspace, or planar reflections, the problem remains. Here is how the bug looks like.

This looks like some reflection artifact. If I look at my mirror (or any other reflection object in the scene), all the reflecting objects seem distorted. The distortion is barley influenced by any settings, even the resolution (which i’ve set to max). But the strangest thing is, that I can see a normal reflection. But I have to look from a very large angle at the mirror.

I’ve tried almost anything by now, and I am desperate. None seem to have had this problem. Idk what to do next

This is how lumen works when set to software Ray tracing. The “distorted” reflection you are seeing is the “surface cache” which is a low quality representation of your scene which allows it to quickly raytrace.
You can improve the quality by enabling Hardware Raytracing and Hit Lighting in the Lumen Settings.
The reason it looks better from some angles is because objects that are on screen will use screen tracing instead of the surface cache, which allows their full detail to be shown.
