Prevent picom from adding transparency to client title

[vendion]

I'm trying to work out how to prevent picom from adding transparency to the title bar on clients, but no clue what the class to use in picom is for it. I've tried _HERBST_TITLE as my best guess, but that didn't work.

With picom running:

Without picom:

$ xprop -frame
WM_CLASS(STRING) = "_HERBST_DECORATION", "_HERBST_DECORATION"

Ahh I was using xprop without the frame argument so I just kept getting the client window information. Thank you!
