Bro, read my thread. I had these problems and worse. This seemed to finally fix it. https://community.amd.com/message/2922518?commentID=2922518#comment-2922518
Duuuuudddeeee, just downgraded to 19.7.2 and im running GTAV! Lol this is crazy, I hope none of my other games stop working.
Adrenalin 19.7.4 is out which fixes GTA V.
