The 20.4.2 version of the Adrenalin graphics driver is the only version that dosen't give me troubles. Every version after that makes Substance Painter and Marmoset Toolbag 3 stop working propely.
So many drivers launched since the 20.4.2 and I still got problems! I have a RX 5700 XT and a R5 3600.
New driver release, 21.2.1, still with the same problems! 15 drivers releases since there and counting...
