When updating to the latest driver which is 22.6.1 or earlier (2021), some games won't work well and displays rainbow artifact.
Two of the games I encounter with this issue is Valorant and Fortnite. It only occurs during full screen mode no matter what resolution it is.
Though, when downgrading the drivers like the 2020 adrenaline, it works fine and shows no rainbow glitch or something but still it's good to have the latest drivers.
Here is my specs:
AMD A8-7500
R7 integrated graphics
RAMSTA A88k FM2+
DDR3 1600Mhz Faspeed 8x2
If you ever know the solution, please tell me and thank you in advance!
