Christopher, I submitted the information through apport like you asked. Since I'm not familiar with this, and it took me some install steps, I hope all went well.
I also realised that with my last message, I may have followed the wrong link, hence tested the wrong versions. That is why I did the test I described in my last message again. The results are below are interesting. You can find them in the csv I attached. Since our i386 is single screen only, I was not able to test the dual screen set up performance. The ones labeled "Production" are of course our normal production machines, the installs that prompted us to file the bug report. Fed by some online reading, I'd think xfdesktop4 might be the culprit? But then again, I'm just a simple user. Just to be sure I noted the xfdesktop4 version numbers also for you. I also saw that the icon rearranging bug has also been reported with xfdesktop4 4.12 (see Bug 1335492 and 1307251). I however have not been able to reproduce it, even after 10+ reboots.
