How many brightness steps does your laptop support? Please provide the output of $ qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement/Actions/BrightnessControl org.kde.Solid.PowerManagement.Actions.BrightnessControl.brightnessMax

Can you add a screen recording showing what it looks like for you? Either way the correct solution would be to fix the flickering, not revert the feature entirely.

I was pretty sure it would not animate for less than a certain amount of steps.

Honor animation brightness threshold also for sysfs helper We should only animate the screen brightness if there are enough steps available to make for a smooth transition. This check was forgotten for the new sysfs brightness animation.
