Allow dwm to have translucent bars, while keeping all the text on it opaque, just like the alpha-patch for st.
Fix transparent borders
By default dwm might make windows' borders transparent when using composit window manager (e.g. xcompmgr, picom). Alpha patch allows to make borders opaque.
If all you want is to make borders opaque, you don't care about statusbar opacity and/or have problems applying alpha patch, then you might use fixborders patch instead.
