Comment 8 for bug 1283664

Looking at the CPU history rolling graph, it shows a 100% reading on one (of my four) cpus for about 1 second which freezes both mouse and keyboard activity.
The freeze occurs immediately after the background wallpaper has finished changing.
Making changes to the settings within the backgrounds system setting panel has no effect (except to change the timing of the freeze occurance which is always linked to the time interval chosen for the background to change).
My backgrounds are from a directory of my own (within Pictures) but the freeze still happens with the Sarah or Serena pix directories.
When I reboot, there is an (undetermined) interval before it starts to freeze.

I am running Mint 18.1 64-bit, Cinnamon 3.2.7, Kernel 4.4.0-21-generic on an AMD Athlon II 640 x4. Graphics is AMD/ATI Oland Pro (Radeon 240/340) VGA controller.

As Wojtek says - it is nice to see the pictures change!
