Hi again! Time to open this topic again, since it hasn’t been solved.
I’ve reached the conclusion that the bug is located in the ‘Color Grading’ property in PostprocessVolume. When enable, the “red noise” is likely to appear when opening level/starting game (note: the red noise doesn’t always appears, but quite frequentely)
If you change the Color Grading Intensity settings in level blueprint as I described in my answer above, the red noise disappears BUT so does the color grading. And if you try to enable color grading in level blueprint the red noise appears again… Therefore, currently, you have to choose between either 1) disable color grading and get no red noise, or 2) enable color grading and get red noise.
Obviously, I want to enable color grading without getting red noise. Would very much appreciate if someone could fix this or help me come up with a work-around soloution.
Thank you
