PWM

I used the laptop for a long time at 40% brightness (and OLED Flicker Free Dimming 100%), while not experiencing problems from PWM.
Less than a week ago, MyASUS was updated (to version 3.1.13.0) and ASUS System Control Interface v3 (to version 3.1.10.0)
Now at 40% brightness (and OLED Flicker Free Dimming 100%), I feel discomfort from PWM...
I tried setting brightness to 60% and OLED Flicker Free Dimming to 80%
The situation has improved, but I still experience discomfort from PWM ...
I tried uninstalling the video drivers from Intel and installing the previous version V30.0.100.9929 - It did not help.
I tried to reinstall the version of ASUS System Control Interface v3 to version V3.1.8.0 - it did not help because as soon as I opened MyASUS, the version was immediately updated to the current one.
Resetting Windows didn't help either.
What else can be done?

A laptop:
Vivobook Pro 14X OLED (N7400\X7400PC)
OS Windows 11 22H2 (22621.963)
BIOS version 301
MyASUS 3.1.13.0
ASUS System Control Interface v3 3.1.10.0

After updating ASUS System Control Interface v3 to version 3.1.11.0

This is what is observed!

Video 1 

Brightness 60%
OLED Flicker Free Dimming to 80%

You can see the PWM.

Video 2 

Brightness 40%
OLED Flicker Free Dimming to 100%

PWM is on the rise!

The service center said there was a problem with the drivers, referring to the fact that the developers should fix the drivers.

Will you pass my information/video to the developers?
