• Related to Vulkan Mobile backend: Some advanced debug draw modes do nothing when enabled #55900.

As far as I know, none of the debug draw modes are currently implemented in OpenGL. Not all of them make sense given the features supported by OpenGL, but the basic 4 debug draw modes (wireframe, overdraw, lighting, unshaded) should all be able to be made functional.
