I have a Lenovo E585 w/ a Ryzen 5 2500U. I'm having the same issues, horizontal screen tears, parts of a window showing up where they shouldn't. It's mostly on Firefox, but happens when I view PDFs as well. I'm getting different problems on Steam, there it's small colored squares that flash on and off. I'm also having a problem where every time I wake from sleep I get a black screen, not sure if related but maybe it is? I'm happy to upload lspci and dmesg info if that would help!
