You can switch from Xorg modesetting driver to the xf86-video-ati radeon driver by setting `modeset=0` kernel parameter and installing the `xserver-xorg-video-radeon` on Ubuntu 19.04.
The very least the Xorg log now says "RADEON(0)" instead of "modeset(0)", I hope this fixes the terrible, terrible bug.
