When does it happen? What's in your screen when it's happening?S21U, One UI 4, latest update is working well, power save mode with 120hz, thank you!
One issue i've noticed is when I have 48hz enabled, and the refresh rate monitor turned on, i noticed the refresh rate fluctuates from 48 to 60 to 120 pretty quickly without me touching the screen or anything. it doesnt stay at 48 for more than 5 seconds. is this due to the workaround for 120hz in PSM?
