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.
