This happened to me after running 'unity --replace' to workaround another bug(#1311316). It has happened to me several times before. I attached the full console output here is an excerpt:
$ unity --replace ....

Matching subscriptions: dx-packages https://bugs.launchpad.net/bugs/1310316 Title: Text scaling factor changing unexpectedly Status in Unity: Confirmed Status in unity package in Ubuntu: Incomplete Bug description: I have a MacBook pro with a Retina display. I have set the "Scale for menu and title bars" setting (into Settings > Displays) to 1.5 to make the UI looks good on my screen. That works very well. But sometimes, usually after logging, all the fonts of the UI become much bigger. When that happen I open unity tweat tool and notice that the text scaling factor changed to 2.25. If I reset it to 1 the all the fonts go back to normal. The problem does not happen all the time. I would say it happen one time out of three logging. It may also happen when installing applications from the software center. I have yet to find a procedure to reproduce it all the times.
