Comment 7 for bug 1383745

FYI, I had this again on the latest rtm-proposed image and I can also confirm that restarting lightdm fixed the issue.

I see a similar drop in memory usage before and after [0], but this could just be due to apps closing (I had gmail and telegram open before restarting lightdm)
