Weird artifacting/pixelation when using light sources.

This issue has been happening for a while now, not sure if it is software or GPU related. But the cause seems to be using too much light sources.

For reference, here is an example of what I am talking about:

I achieved this effect on sketchup by using an array tool and multiple light sources:

the issue seems to go away when reducing the overall light sources in the project, but I can reach the desired effect if I do so.

Things that I have tried so far:
Updating enscape and nvidia Driver
reinstalling enscape and driver
tweaking enscape rendering settings
tweaking Nvidia Control panel settings

(GPU: Nvidia RTX 3060)

Would appreciate if anyone knows of a fix/workaround to this issue.
