Decal Rendering in Front of Textrender

I have some decal components that are rendering in front of some textrender components regardless of position, as in the textrender components are transparent for decals.

They don’t seem to operate on the same render order / depth priority lists. How do I set it so this does not happen? I am using 4.10 from source. I can’t seem to find anything on the topic.

Despite saying “This should generally be true for all objects” in the description, UseAsOccluder is not.

TextRender.bUseAsOccluder = 1;
