--- Comment #1 from fin4478@hotmail.com --- With win10 you use latest GPU drivers. It is the same thing with rolling release Linux operating systems, your GPU drivers need to be up to date. Use the latest AMD wip kernel, latest GPU firmware files, Mesa development git and LLVM development git. The Xfce desktop with lightdm is stable when many others are not. Debian buster/sid is a stable ubuntu compatible rolling release OS.
