This is a bug report.

I noticed that if I have two 'different' images as background on my two monitors when taking a snapshot of the screen as Fences does, the image that appears in the subsection entitled 'Layout Snapshots' does not duplicate the screen correctly. It duplicates whatever background I have for my primary monitor.

However, if I restore this snapshot it does not replace the image I have on the secondary monitor with the one contained in the snapshot.

Although this is a minor flaw, I thought you should be made aware of it.
