I've described my problem in this discussion:
sheeshkinAfter 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.

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)
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.

D_IMANPWM flickering will not disappear anyway. It’s normal for OLEDhttps://zentalk.asus.com/en/discussion/comment/220582#Comment_220582
And if those files are not deleted, but simply transferred somewhere, and then, in which case, returned back?
For PWM.
My eyes get tired quickly...

D_IMANNo. PWM technology of reducing screen brightness doesn’t depend on software and drivers as I know.https://zentalk.asus.com/en/discussion/comment/220625#Comment_220625

D_IMANOLED Flicker Free Diminning just changes colors on your screen. Makes them darker.https://zentalk.asus.com/en/discussion/comment/220792#Comment_220792
