Light Flickering with 'Number of Lights' on High

When spamming a skill that generates many light sources (flamewall in my case) other lights in the area can begin to flicker. This happens regardless of shadow/GI settings.

My specs are: NVidia RTX 4070 Ti Super, AMD 9800X3D, 2560x1440p resolution, 60hz, DX12.

Here is an example in the shrine hideout: https://youtu.be/V6x6wldu2JE
