About the "Failed to load" messages. Does it help if you install this libraries in both architectures in the VM? apt install libgl1:amd64 libgl1:i386 libvulkan1:amd64 libvulkan1:i386
I can confirm that this fixes the issue on both VirtualBox and real hardware and has it behave the same as *buntu 20 (including the two other small issues being present still).
This also solves an issue with the non-trial version of Fate/stay night, specifically the fan-made "Ultimate Edition" patch, where it'd have a completely black program window even in fullscreen (though Ultimate Edition uses borderless window rather than exclusive fullscreen, therefore it makes sense that toggling fullscreen didn't solve that issue).
Now the real question is, does this mean that the recommended wine packages for Ubuntu need to be updated so that they also include libgl and libvulkan when installing, or does it just mean that the instructions on https://wiki.winehq.org/ubuntu are outdated?
