HyunSikWoo Hey i got same issue today i was watching One piece latest episode after 24minutes I could see some visible shade line the part where video was playing after 30minutes the shade was gone And more off i have a Brandnew device i think it is cause of update because in Nothing OS 2.5 i never encountered this issue
And i was Watching on Crunchyrool In HDR
I am also confused is it software or hardware issue
