Hello, there is a really bad regression in the Cinnamon desktop with the
20160924 update of Tumbleweed. I depend on the workflow of saving in-progress
documents and downloads to my ~/Desktop and then working on them from there.
Now, this update has completely broken the desktop icon functionality, since
re-painting the Desktop (rendered with Nemo) appears to be broken. When a
desktop icon is selected, the selected color remains after clicking other
icons. The drag-select rectangle color also remains on the screen. I am
attaching a screenshot.

The Nemo file manager in a separate window still works correctly.

I have tried with the default Adwaita GTK theme and with all of the other GTK
themes I have installed, and they all respond the same.
