What does "ssd" mean in this context? I'm guessing it's not solid state drive since that doesn't make any sense in these sentences, but searching that acronym isn't very helpful.
Edit: I guess it means "server side decorations". I see that OP did use the full phrase once, but it didn't click with me initially. Wikipedia says that means the window manager draws titlebar buttons, as opposed to client side decorations which enables the app developer to control the titlebar of their app.
Aha oops I edited at the same time as your reply! Thanks for the elaboration, that's helpful!
