Crash with mesa-git and wayland about airshipper

[rosefromthedead]

@TheJackiMonster airshipper does not use vulkan directly, it uses iced (and iced-wgpu), which in turn interact with vulkan. The driver selection is handled by iced.

I do not use Wayland myself so it's going to be hard for me to find the cause and fix it. I can only recommend using the cli then :/

The cause of this is the wrong vulkan impl being selected - lavapipe is a software renderer and also doesn't seem to like working on wayland. It's happening on my machine but can be fixed by specifying VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.x86_64.json to force it to use radv instead of lavapipe. I don't know why lavapipe is being selected at all, given all other vulkan apps on my system happily choose radv by default. I just ran an example from iced master and can confirm it selected radv on its own (and fwiw also doesn't work if i specify lavapipe) - maybe this can be fixed by just updating iced?

@rosehuds I have also some experience with Vulkan. If that's the issue then the application has to select the proper device to fix this. Generally you can specify exactly which physical device to use in the Vulkan API (depending on features, index, extensions or name). So this should be something to fix on application level.
