pcmanfm-qt does not resize root window when desktop size changes

[Kamilion]

VMWare ESXi 5.x (IDE disk) Netinstall of Xenial 2015-12-10, "lxqt-metapackage openbox qupzilla obconf lubuntu-artwork" following https://wiki.ubuntu.com/Lubuntu/LXQt#Installing_LXQt_on_fresh_system

Rebooted, First thing I did after logging in was try to change resolutions.
The display dimensions change, but pcmanfm-qt's root window does not.

Workaround: Open the LXQT Session Settings applet, select "Desktop", press the "Stop" Button, then the "Start" button.

Screenshots are attached.

Workaround: Stop, and then Start the "Desktop" from the LXQT Session Settings applet.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug affects me too, and I made some observations about what happens when the desktop is right clicked.

Observe that the menu outside the root window is the openbox menu.

should be tested with a current xenial version of pcmanfm-qt, btw. the bug is fixed upstream, but i don't know if this fix has reached xenial in time.
