Summary:                    Stops responding and takes CPU on workspace switching
Description: 
Occasionally when I switch workspaces, xfwm4 stops responding. I can still
type in the window with focus, but moving windows, creating new windows
(including menus), and switching workspaces is not possible. top shows
that xfwm4 is taking over 90% of the CPU. killall xfwm4 does not work.
killall -KILL xfwm4 does, but also restarts the X session. This time it
happened I captured a backtrace using gdb.

I'm using the debian package, version 4.0.3.1-2. Please let me know if
there is anything else I can do to help track this down next time it
happens.

Thanks
James

Humm, never heard of any similar problem. The loop seems to occur in gtk,
anything special about your install?

PS: You may update to the latest xfce release.

Cheers,
Olivier.

Also, the killall -KILL xfwm4 should not restart your session as xfwm4
doesn't control it (on a "normal" install)

Also if you could identify the exact sequence that leads to this, that
would help... What apps are running, what few actions you perform just
before the problem arises, what seettings you hav set (focus mode, auto
raise, etc.)

TIA
Olivier.

I can't think of anything special about my install. I'm using the debian
unstable packages.

.xsession contains this:

/usr/bin/xfce-mcs-manager
export TERMCMD=gnome-terminal
/usr/bin/xfwm4 --daemon
xscreensaver &
gdesklets &
exec /usr/bin/xfce4-panel

.xfce4/settings/xfwm4.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mcs-option SYSTEM "mcs-option.dtd">
 
<mcs-option>
        <option name="Xfwm/BoxMove" type="int" value="0"/>
        <option name="Xfwm/BoxResize" type="int" value="0"/>
        <option name="Xfwm/ButtonLayout" type="string" value="O|HMC"/>
        <option name="Xfwm/ClickToFocus" type="int" value="0"/>
        <option name="Xfwm/DblClickAction" type="string" value="shade"/>
        <option name="Xfwm/FocusNewWindow" type="int" value="1"/>

        <option name="Xfwm/RaiseDelay" type="int" value="250"/>
        <option name="Xfwm/RaiseOnClick" type="int" value="0"/>
        <option name="Xfwm/SnapToBorder" type="int" value="1"/>
        <option name="Xfwm/SnapToWindows" type="int" value="1"/>
        <option name="Xfwm/SnapWidth" type="int" value="10"/>
        <option name="Xfwm/ThemeName" type="string" value="ops"/>
        <option name="Xfwm/TitleAlign" type="string" value="left"/>
        <option name="Xfwm/TitleFont" type="string" value="Impact 13"/>
        <option name="Xfwm/WrapResistance" type="int" value="10"/>
        <option name="Xfwm/WrapWindows" type="int" value="1"/>
        <option name="Xfwm/WrapWorkspaces" type="int" value="0"/>
</mcs-option>

I'll see if I can reproduce the crash.

Please make sure you try either xfwm-4.0.4 or this preview version:
