I think someone has a LD_PRELOAD library lying somewhere on the Internet that forces GTK+3 to not draw a header bar and to use a normal decoration instead. But I have no idea where it is and how stable it is. The only supported way of enforcing a SSD is to ignore the fact that the client wants to draw their own decoration and always draw on. The gtk.css bit is just a courtesy to make it look less clunky. Yes, you will have double decorations. That is unavoidable (and, I should say, not Xfce's fault in the slightest).<br><br></span></div><span>Best of luck,<br></span></div><div class="gmail_extra"><div><div class="h5"><br><div class="gmail_quote">On 15 June 2016 at 21:01, Klaus Zeitler <span dir="ltr"><<a href="mailto:info@klauszeitler.de" target="_blank">info@klauszeitler.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello,<br>
seems that Xfce 4.12, that comes with openSUSE 42.1, has now enabled CSD.<br>
Some applications, e.g. eog, evince, gedit etc. pop up without the<br>
usual frames and header bar. I guess this is due to GTK 3 CSD.<br>
I would have thought, that there should be a (fairly) simple way<br>
to turn CSD off, but I couldn't find anything (neither in GTK docu nor<br>
for Xfce). I hope I just missed it. The only thing I found (but haven't<br>
tried yet) is gtk3-nocsd. This looks like quite desperate measures.<br>
Is there a way to turn CSD feature off in Xfce or in GTK config?<br>
