@MisterRedTurtle Did some further troubleshooting and noticed that certain sets of light sources were producing the weird flashing lights.

In this gif, I had selected a group of light sources that was causing a portion of the light flashing issues. I noticed that turning off the shadow property of these sources solved the light flashing.
I guess that somehow, for these light sources, there are issues with producing the shadows? For this specific group of light sources, this has been an easy fix without effecting the original intended lighting effect. However, there will likely be light sources for which turning off shadows would not be ideal for the aesthetic of the build. It’s also gonna be a bit tedious to go through all the light sources and locate those which are causing the flashing.
