Display colors change with refresh rate

Star II
The screen colors/contrast are slightly different at different refresh rates. With auto, it flickers.
In 90Hz color reproduction is bad, it gets a blueish hue.
Model Name: zf9
Firmware Version: 32.2040.2040.23
Rooted or not: nope
Frequency of Occurrence: permanent
Workaround: fix refresh rate.
Steps to replicate:
Dark mode
Switch display mode/colour profile to "neutral"
Place refresh rate toggle as first quick setting in notification shade
Decrease brightness to minimum
Pull down notification shade
Switch between refresh rates using the toggle and observe the gray background of the notification shade changing hue/color.

Another, slightly more way:
Enable auto refresh rate
Take many high dynamic range photos with whichever app
Brightness to minimum
Open Google photos
Start scrolling, and observe color changes between scrolling and not scrolling


Hey @Martreb2000, I heard back from the R&D team.
In the first scenario, the screen flash issue is due to a hardware limitation since the screen flashes rate supported by each APP and interface is different, this is a normal reaction that the naked eye may see when switching
You can fix the screen flashes rate at 60hz if they feel troubled.
As for the second scenario, the R&D could not replicate the issue, so they require your assistance for further investigation-
Go to the developer options, and enable the display screen refresh rate
Activate the log
Recreate the issue by opening google photos, slide the down page, and observe whether the displayed fps changes (normally it should be fixed at 60)
Save and send the log.
Please follow the below steps to activate the built-in log tool (Bug reporter).
1.  Open “Calculator APP”
2.  Enter “.19595+=”
3.  Select the Log type according to the type of issue you want to capture. “General cases” will work for most issues.
4.  After your selection the log tool will exit so you can duplicate the issue or wait for it to happen. Try to use the screen recorder to show your issue when possible. If you can't screen record your issue, then please take a screenshot right after the issue has occurred (as a timestamp) so we know where to look in the log.
5.  Navigate back to the log tool via calculator and Tap "FINISH AND SHARE".
6. It takes several minutes for the log to generate. You can exit and do other stuff in the meantime. A silent notification will tell you once the process is done. Tap the notification and then the share button to upload the file to Google Drive and share the link with a moderator. Just make sure to change the permission first so that everyone with the link has permission to view it.
Note: When you're no longer planning on logging your device, enter “.09595+=” in the calculator and the log tool will stop as well as deleting all stored log files. Make sure to share via calculator. The files found in internal storage -> asus_log are not the correct files (they are only 1.2kb).
You can share the log with me via PM.

This problem has already been addressed. It is due to the poorly calibrated 90Hz mode. If it bothers you - like me - you have to switch to a constant refresh rate. Asus does not seem to want to do anything about this.
