Reproduction

Create a new prefix with:

export WINEPREFIX=~/SteamLibrary/steamapps/compatdata/359320/pfx
rm -rf $WINEPREFIX
winetricks -q dotnet40 vcrun2015 win7 dxvk

The reason for this can be found here: https://github.com/redmcg/wine/wiki#the-official-build-of-proton-42-runs-ed

After that start Elite Dangerous with VK_ICD_FILENAMES="/usr/share/vulkan/icd.d/amd_icd64.json" PROTON_NO_ESYNC=1 %command%
The VK_ICD part is supposedly workaround to use radv instead of amdvlk as reported here to prevent exactly the problem I'm facing.
It does not matter though, even without any modified launch options the same problem occurs.

I believe, that the VK_ICD_FILENAMES variable is not being passed to the Elite Dangerous process itself from the launcher. I already used it in X4: Foundations and that worked great.
