 Hmm, it is not quite that simpel to reproduce - have to investigate more,
 it sometimes works, maybe some xf*d does not startup properly/automatically
 in my setup?

 I start from xdm and have this in my .xsession:

 --8<--
 #! /bin/sh

 eval `dbus-launch --sh-syntax --exit-with-session`
 exec startxfce4
 -->8--

 I see similar issues actually. As far as I can tell, xfwm4 wedges
 itself at some point when you move a window -- the first time works,
 then it somehow hangs. You may notice that in this situation,
 right-click on a title bar does not bring up a context menu.

 In this situation, you can still "pkill xfwm4", at which point
 xfce4-session will relaunch it and it will work again for a while.

 Martin: would you like me to downgrade the package for now?

 No hurry, let's diagnose and fix in-time for the next quarterly release.

 I'm not able to reproduce this with xfwm4 4.13.1 on NetBSD-8.0_STABLE,
 using Intel integrated graphics on a T420. Dragging windows still
 works consistently for me. Could there be some difference between X11
 releases or the DRM stack in use that could explain this?

 Maybe. My setup is:

 - NetBSD 8.99.25
 - Intel DRM
 - Modular X11 from pkgsrc, including xf86-video-intel-git

 Martin, what setup are you on?

 I should have added, I'm using X11 from NetBSD base, not the modular
 version from pkgsrc.

 I have NetBSD 8.99.25, Radeon, X11 from base.

 Hi,

 can someone with the problem send the following:

 - Output of 'glxinfo'
 - config.log for xfce4-wm, (does it have HAVE_PRESENT_EXTENSION)
 Or,
 - output of `xfwm4 --version`


 Going by a diff,


 +4.3) VSYNC and tearing
 +======================
 +
 +Starting with version 4.13, xfwm4 now supports VSYNC via two different
 +method, either using OpenGL or the Present X11 extension.
 +
 +xfwm4 relies on libepoxy for OpenGL, and on libXpresent for Present support.
 +
 +Support for those features can be checked using "xfwm4 --version":
 +
 +	Build configuration and supported features:
 +        ...
 +	- Xpresent support:                             Yes
 +	- Embedded compositor:                          Yes
 +	- Epoxy support:                                Yes
 +        ...
 +
 +If both VSYNC methods are available, xfwm4 will prefer Present over OpenGL.

 I can imagine a scenario where it waits for a vblank to update the
 changed windows but it never comes.

 It would be nice if someone is adventurous, to force disable xpresent.
 Add
 CONFIGURE_ARGS+=--disable-xpresent
 to xfce4-wm Makefile, make replace.

 Thanks.

 What setup works and what setup fails?

 I get the impression:

 netbsd-8		base xsrc		intel	OK
 netbsd-current		base xsrc		radeon	BAD

 What about benny?
 And which radeon is it?

 I've done so, and am running with Xpresent disabled now. It works, but
 there is some weirdness with windows I wasn't seeing before. (I'm the
 "known good" case with 8.0_STABLE/amd64/base X.org/Intel.) They can get
 into a state where they start repositioning themselves when I try to
 simply move the mouse pointer, and also sometimes refuse to resize and
 such. Other than that, I'm not seeing any problems, so far.

 Upstream seems to be heading toward a new release and we have an old
 developement version of xfwm4 in pkgsrc. Maybe time to try their release
 candidate instead?

 Benny, could you have a look?
