Indeed ;)

Could also be selinux.

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).
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.

Saw your patch for that, thanks.

They should have done that in 3.16 IMO ...
