Hi,
I can't give any R-b, because that would require really digging into

Indeed ;)
so it looks fine to me. If it would compile, that is, see below.
(It does work with Gtk 2, though)
((at least on my laptop with mesa; on my desktop with fglrx, creating
the shader fails, which may or may not have to do something with
"libEGL warning: DRI2: failed to authenticate" (which is probably in
turn my own fault for using a proprietary driver)))
Could also be selinux.
Except I don't use SELinux (here). I know, I know, shame on me.

Yep, that is a bit awkward.
Deprecated because gtk_widget_set_double_buffered() doesn't work with
the wayland backend. The switch simply doesn't make sense with the
wayland rendering pipeline, and the egl rendering might not work on
wayland because of that (/me didn't try).
Right, but we cannot really tell gtk that we know what we're doing. :-)
Nevertheless gtk_widget_set_double_buffered() is required to make gl
rendering work (on X11 backend), for versions older than 3.16. On 3.16+
we can use the opengl support provided by gtk instead. Code for that
still needs to be written though.
Yep, that's what I thought of, too. But the problem is, as you yourself
say, that 3.14 < 3.16...

But then again it didn't compile before, either: qemu/ui/gtk.c:1927:5:
Fehler: »gdk_cursor_new« is deprecated (declared

Saw your patch for that, thanks.
gtk_widget_set_double_buffered() was deprecated in 3.14 already (as
far as I can see from the header file alone).
They should have done that in 3.16 IMO ...
cheers,
Gerd
