I missed a whole conversation while I was away huh lol. So let’s see here, you’re mentioning LUT’s and the Sega Luma Fix setting, all of those settings above “LUT” in the parameters are not guest advanced settings at all, those are from the “grade” shader which Dogway is the author of, I just combined it with guest.r’s shader for my own wacky lab experiments.
Not sure how much I can help in that area, the last biggest issue concerning grade shader settings were that all Linux users were experimencing a “black screen but can still hear audio” all due to the “contrast” setting in grade. I have since disabled that setting for a few months now. I then read at one time that Xbox series users were experiencing weird colors no matter the preset, not sure if that issue has been resolved but I don’t see those kind of posts anymore.
Basically I’m trying to say I think the grade shader affects different systems/operating systems in different ways so I really can’t explain why you’re seeing those issues with those specific settings. I know I never touch that LUT 2 settings because it messes up my colors and I don’t use the Sega Luma Fix because my presets are more “universal” that can be applied to any console. That setting is strictly for Sega machines, can’t have that pre enabled when it’s time to throw on a nes, snes game etc.
You probably will get better answers from Dogway himself but he’s hardly ever around these days, I tried learning as much as I could from him when he was around a few months ago but then he dissapeared again.
Edit: Actually I’m curious about this. Your issue doesn’t happen on my end but I want to know why it’s happening to you so let’s try this first. @DukeSkinny can you go into the parameters and try setting all 4 of those “Black” setting back to 0:
Let’s see if that makes a difference first. I forgot exactly why I even tweaked those settings myself, I was just trying out different things so I want to see if disabling those will possibly fix your issue. If not we’ll try something else.
