Do you have DisplayFusion managing your wallpaper? If so, you can try disabling "Automatically pick an accent colour from my background" in the Windows Settings > Personalization > Colours panel, and see if that helps.
Thanks!

Hi Owen. Yes I have displayfusion managing my wallpaper for me and accent color is set to manual but the shutter if still there. 
About my setting, I have dual monitor slideshowing different wallpaper (1 from 2k wallpaper and 1 from 13k wallpaper). Frequency ~1 min per change. At the beginning I thought it was something related to displayfusion / my wallpaper but after testing the windows service with some smaller folder I realize the problem is windows itself. 
I have single graphic card (3080), no intergrated graphic card. 
Thanks for your help!

Thanks!
