--- Comment #8 from Paul Menzel pmenzel+bugs.freedesktop.org@molgen.mpg.de --- libXpresent was not installed here, so xfwm didn’t have support for it.
``` $ xfwm4 --version This is xfwm4 version 4.13.1 (revision 942156e4) for Xfce 4.12 Released under the terms of the GNU General Public License. Compiled against GTK+-3.22.30, using GTK+-3.22.30.
Build configuration and supported features: - Startup notification support: Yes - XSync support: Yes - Render support: Yes - Xrandr support: Yes - Xpresent support: No - Embedded compositor: Yes - Epoxy support: Yes - KDE systray proxy (deprecated): No ```
Installing libXpresent and rebuilding xfwm, the report that everything works now.
As I do not know the dependencies between all components, I cannot say, that it’s really no driver bug.
