The Radeon Open Driver was working fine on Ubuntu 16.04 with my Radeon R9 280x. But I just upgraded to Ubuntu 17.10 and it's not working properly now.
There are visible artifacts while resizing various windows.
3D applications are unusable, significant performance decrease(5fps), also some weird stuff with colors.
P.S. First time reporting bug here, I apologize for any wrong-doings I might be doing.
