What causes those weird artifacts? They suddenly appeared.

As you can see in the screenshots i attached im getting really weird artifacts in my scene. Im Using Lumen and its a scene from Archinteriors, i did not change any settings.

The problem suddenly appeared, in the beginning everything was fine. When i click start everything is fine again, its only in the viewport while editing.

Any ideas what could be the problem? Im running the scene on UE 5.3.2 and i also tried 5.4.1 with no success.

Thanks for any help!

did you updated the nvidia drivers? I had the same with the latest one (v555.85) I had to roll back way to driver version v537.58 and it’s fixed now
