FlickerFix for Forge 1.16.4 - disable nightvision flickering
By default, when the night vision effect goes below 10 seconds, the screen starts flickering. This mod replaces that behavior with a fast fade-out at 1 second remaining duration.
This mod is likely to be incompatible with any other mod that provides a Mixin for GameRenderer.getNightVisionBrightness(LivingEntity, float).
