Unplugging secondary HDMI monitor messes up Wallpaper

[dbum]

When I plug in my TV over HDMI everything works fine. But when I unplug it, my wallpaper gets shifted wierdly.

I want to apologize if this is a bit brash, but it's best explained with 4 screenshots:

before:

with secondary screen plugged in:

when secondary screen was unplugged:

2nd screen attached again:

Happens reproducable, every time I unplug an HDMI monitor. When it happened, also, a right click on the desktop doesn't open a context menu anymore. Restarting Cinnamon doesn't help, I have to restart the x server / log in and out.

Can you try this with Gnome Shell?

I have a similar issue with muffin and cinnamon master on F17

I have a single monitor setup using DVI output and can't reproduce it with gnome-shell.
