Similar to Clustertruck (see my forum contribution "Game stuck in selection menu (HW requirements not met?)")
Filament has high needs for its graphics using Vulkan.
But at least it does warn the user about a non-conformant Vulkan implementation.
Without a conformant Vulkan you will see flashing graphics errors (even in 1st selection menue),
so for Navi 10 (aka AMD Radeon RX 5700 XT) you should have Mesa 20.0 or higher
(e.g. in Ubuntu 20.04.0 [Focal] {default: 20.0} or otherwise via Mesa 20.1.2 for
Ubuntu 19.10 [Eoan] or Ubuntu 18.04.4 LTS HWE [Bionic] {both by default 19.3}
or for Focal from `Mesa Almost Stable PPA':
* [url=https://launchpad.net/~ernstp/+archive/ubuntu/mesarc]https://launchpad.net/~ernstp/+archive/ubuntu/mesarc[/url]
best combined with Linux 5.7.6+ from vanilla kernel PPA:
* [url=https://kernel.ubuntu.com/~kernel-ppa/mainline]https://kernel.ubuntu.com/~kernel-ppa/mainline[/url] ).
After this, Vulkan is conformant (but maybe not recognized by vulkaninfo of Bionic {not updated with Mesa PPA and thus way too old}).
