Detailed description:

The display of vivobook pro 15 oled flickers/flashes. It looks like color shifting or randomly petty brightness changing for a second especially noticeable by gray color in the dark theme of windows 11. I mostly see this issue in windows explorer when just moving a cursor. It happen when AMD Radeon Adapter is enabled in Device Manager. It doesn't depend on drivers cos i've tried several types (recommended by ASUS, by Microsoft and the newest from AMD). The problem doesn't exist when AMD Radeon Graphics adapter is disabled. It also doesn't happen in safe mode and BIOS regardless of graphics adapter.

I've done all recommendations from costumer supporters and internet sources.

Vivobook OLED display issue (color shifting/flashing)
After more than a month of repairing (screen matrix was replaced in local authorized service center) the problem with the display still exists. The phenomenon is not caused by a matrix defect.
Agents from local ASUS Support Center and local service center declared that this phenomenon is not a laptop defect. But they don't provide me with proofs and any technical information about this phenomenon.
I assume that the local office doesn’t want to solve this problem and try to convince me that this phenomenon is not a defect.
I want to know exactly why it's not a defect (technical information)? I want to be provided with full explanation of this phenomenon to make sure that it's really normal condition for my laptop.
You can check the problem in the video below:
It's random flashes (brightness changes for a moment). This issue happens just while moving a cursor. It's mostly noticeable on gray color on display (for example Windows Explorer with the dark theme of Windows 11). It doesn't depend on versions of chipset or GPU drivers and BIOS. It happens when AMD Radeon Adapter is enabled in Device Manager. The problem doesn't exist when AMD Radeon Graphics adapter is disabled. It also doesn't happen in safe mode and BIOS regardless of graphics adapter.
My opinion: the problem is related to the ASUS software and its driver conflicts.
UPD: This is not a PWM effect because I see the phenomenon on 100% dsiplay brighness.

OLED Flicker Free Diminning just changes colors on your screen. Makes them darker.

This function doesn’t work on your device?

Yes, it doesn't work for me...

I'm waiting for the developers to release a new version of MyASUS, it seems like they promised to fix this in the new version...

I don't know why, but as soon as I turned down the brightness to 40%, I stopped feeling the PWM!
Before that, the brightness was 50%, I suffered from PWM ...
And this is despite the fact that OLED Flicker Free Diminning and Splendid still do not work...
How is this possible?

Hello!
I notice some random flickering and buggy dimming (random flashes of black, areas that stay dimmed even if focused, etc), when MyAsus Target Mode is enabled (brightness level 60%, OLED Flicker-free Dimming 60%).
Perhaps Target Mode works with PWM dimming?
EDIT: Well, even with Target Mode off, I can still see some random flickering. Perhaps this is due to the Flicker-Free Dimming, which changes color hues?

Even after updating to the latest BIOS version and the MyAsus app being up-to-date, I definitely have this flashing, which is noticeable on darker/grey backgrounds, exactly like in the screen recording that was posted here.
This is a software bug and I hope the developers can replicate it so it can be fixed.

Hi @destel

The developers had tried to reproduce this phenomenon several times starting in May. But still no result as u can see from the reply above.
After months of trying to understand what happens I really don't think it's a software bug. Even considering Splendid (part of MyASUS software) removal had eliminated this bug perfectly.
