A few months ago I ran into a lighting issue right before a big presentation. It took me about a week of trial and error to figure out it was an NVIDIA driver issues. I thought it was the type of lights in the scene and that’s why I switch them in the video but it ended up being the driver 100%
I just had the same thing happen after updating drivers some 4-5 months later and just wanted to mention it and show the video here in case anyone runs into the same issues…Ive been seeing a few posts about it in various UE groups

Not sure what causes it but very annoying - was hoping the new drivers would have fixed it by now but I guess not.
