help!! i installed teh AMD Radeon Adrenalin Edition Graphics Driver 18.2.2 Hotfix update last night and this morning my gaming laptop looked like this in 3D apps:

little colored blocks, flickering lines, sometimes a whole strip of the screen goes green for a moment, it doesn't crash, it just looks horrible. my stomach dropped because artifacts usually mean dying hardware, right?? but it's suspicious that it strated exactly after the update. how do I tell which one it is without spending money?? what am i doing wrong??
