For the information of other AMD users: I have an Asrock deskmini A300 with a Ryzen 2200G and I also have a celeron-based Intel NUC. I have installed Arch Linux many times and I recently tried EndeavourOS on my NUC and the Asrock A300. All went well until I accepted a large upgrade which included Linux Kernel Version 5.2.8 (upgraded from 5.2.7). The NUC was fine, but the Asrock started producing coloured artefacts everywhere the mouse went. I reinstalled vanilla Arch Linux on the Asrock and got the same effect. So, on my Asrock I reverted to the Linux 4.19 LTS kernel (still on vanilla Arch Linux) and peace and sanity was restored. I checked but there appears to be no AMD BIOS update for the 2200G, only for the 3000 series.
