--Update--

While kernel versions 5.3.0-0.rc0.git2.2.fc31.x86_64 and
5.3.0-0.rc0.git2.4.fc31.x86_64 versions of the kernel seemed to be pretty
stable when it came to booting the system / touchscreen working etc, there was
a massive amount of video tearing (within Chrome / Konsole) within my KDE
session, enough to force me to roll back to 5.1.16-300.fc30.x86_64
