Nervous screen dimming

Ubuntu 25.04
Ubuntu 24.04
Pop OS

All with the same issue. Display dimming is extremely nervous. I think iio-sensor polls every second and causes the display dimming to give me a headache. It is constantly correcting, there is no cooldown period, it’s not even smooth.

Any suggestions on how to use automatic display dimming in such a way it doesn’t do these things?

On my phone at work right now, I thought there was a setting in the BIOS to turn it off maybe not though. Alternatively putting a really small piece of black tape over the sensor would stop it from adjusting. Then the brightness could be adjusted manually.

Just my quick thoughts on this.
