I don't Know. All I do is pachage them and check wether or not they work in DD, are in the correct tag, colorable etc. I work on windows 10 and have never worked with linux so.....
I have seen some threads on reddit about the downloaded packs not working. I have also seen packs not show up in the asset menu, if I had many packs installed. Also had packs show up in the item list that I could not turn on or of with the asset manager. If they don't show up at the bottom of the assets when you select "all" in the top right column above the items they are definately not loaded. But not everything is working as it should. Add Linux to that (is there linux support?) and my awnser is I don't know.
