========================================
Ok this is what I notice recently,
No flickering problem on heavy games, Youtube App are fine, video players fine, everything seems normal.
But when go Chrome browser and play an embeded video, or any video on a website, the whole screen brightness flickering, pretty bad, depend on what's in the video,(any brightness level, to put 100% for more visible flickering)
And it only happens on 90hz and 120hz refresh rate
Can anyone do the test to confirm if it is just me?
To test:
Play youtube video on Chrome browser (not the youtube app)
Or play the ff7 remake game review video on gamespot website, that triggers flickering pretty bad for me (i cant post link here)
Please test for me if your phone also flickering by playing this video on Chrome browser at 90hz/120hz
If it's also happen on other user phones, could it be fixed on future update??

Just an update:
It seems that, by disabling video decoding Hardware Acceleration on Chrome browser fixes the screen brightness flickering issue.
Could it be hardware level issue? or driver?
so far no other apps cause this kind of screen brightness flickering,

only happen in android Chrome browser on websites with videos, can anyone confirm this?

I can see the flickering as you mentioned on Chrome. Not on Firefox though, which is my main browser.
So, I would probably say this is a Chrome app issue as the app might not be optimized for ROG.

Chtome isn't optimized for 90 or 120 fps. So it tries to throttle down the screen back to 60 or even 30 fps when a video is playing. The flickering seems to correlate with changing refresh rate suddenly.

Good to hear that it wasn't just my phone, but the chrome app optimization,
Thank you all for the test, hopefully google fix this issue since more and more phones on the market have higher refresh rate screens 🙂
