Does anyone know why this happens when I set the mask strength higher than 50%?
mask at 50%:
mask at 100%:
EDIT: I’m wondering if the mask is actually doing something weird with the LCD’s subpixels when set higher than 50%. When I zoom the second image to max size, I see weird horizontal bars extending across the entire screen, beyond the actual image… The bars are most prominent at the top, middle and bottom of the Super Mario Bros. logo. Also, if I defocus my eyes and look at the second image fully-zoomed in, I can almost see the screen refreshing, almost like CRT flicker. Weird! I’m using a 1080p TN LCD.
