GPU: PowerColor Red Devil Radeon RX 5700 XT using OC BIOS (default)

Stock Fedora 31: Kernel 5.3.8, GNOME 3.34, Mesa 19.2.2, linux-firmware
20190923, LLVM 9.0.0

I experienced frequent hangs using X.org Gnome (Kernel 5.3.7, > Mesa 19.2.0),
especially interacting with graphical file manager-related operations .

Wayland Gnome is much more stable, although I experienced a hang today after
being powered on for almost two hours (45 minutes idle, 75 minutes with high
GPU load). Hang occurred during a gaming cutscene.
