 Solution 1: install Mesa-vulkan-device-select-24.0.8-377.1.x86_64 from vendor
openSUSE
  replacing Mesa-vulkan-device-select-24.0.8-1699.380.pm.1.x86_64 from vendor
http://packman.links2linux.de
 Solution 2: install libvulkan_intel-24.0.9-1699.381.pm.1.x86_64 from vendor
http://packman.links2linux.de
  replacing libvulkan_intel-24.0.8-377.1.x86_64 from vendor openSUSE
 Solution 3: keep obsolete
Mesa-vulkan-device-select-24.0.8-1699.380.pm.1.x86_64
 Solution 4: break libvulkan_intel-24.0.8-377.1.x86_64 by ignoring some of its
