Why do I have flickering in my UE5 scene? (I am a total UE noob xD)

Hi guys, I don’t know why but I seem to be having some major flickering issues within my UE5 scene. I am totally new to Unreal Engine and I am building my first environmtent in it. Is anyone able to help out please?

P.S. I have done some research and it is possibly z-fighting but how do I fix that if it is the problem. Cheers.

I have included a video below showing exactly what is happening.

In fact it’s not normal when Emissive doesn’t flicker, they still need a lot of work, like Emissive doesn’t support shadows, which prevents me from getting UE5 to work on movie projects.

Ahh right, I have been having issues with it for a while and it has been driving me crazy. I guess there isn’t much I can do to resolve it then
