Description
When using the SDF filters on transparent elements, such as the "Text" source, it seems to consider the border of the element as opaque for the purpose of generating outer shadows, outer glows, or outlines. This results in a transparent element showing a border around it when all that's wanted is to have the effect surround the internal elements, such as the aforementioned text.

Which Graphics driver are you using? The outside is supposed to be treated as "infinite distance", instead of "zero distance" which is the default when a graphics driver does not support border sampling.
I'm using the nVidia proprietary driver, version 440.82.
I'm on a Macbook Pro 2019.
I've looked into the OBS code, the OpenGL subsystem in OBS does not set the border color at all. This is an upstream bug that I can't fix, but it might be possible to have a workaround.
Any update on this issue? I have mitigated it by just expanding the edges with a crop/pad filter before SDF and cropping them back out with another filter after SDF, but this solution is a bit silly.
This is still an upstream libOBS issue, the plugin uses the proper libOBS APIs but gets a different result on OpenGL only.
