After recent update 1908.21-0 it seems refresh rate has become slow . 120Hz feels like 90Hz and 90Hz like 60Hz... If you set the rate to 60Hz phone is almost unusable... everything is so laggy and slow. I have OnePlus 6 it's 60Hz is like Rog 2 90Hz
So something has broken after recent update. Is anyone else facing same issue? If not can you please change refresh rate to 60Hz,check and let me know
