+Subject: [PATCH] Check if current GPU supports Vulkan DRM modifiers when
+ `--backend=auto` is used.
+
+This works around #1218 by making use of the new backend option added in #1321,
+but adds a check to automatically fall back to the SDL backend if the current
+GPU does not support Vulkan DRM modifiers.
