This issue is also reproduced in my 14.04 box. In the unity-control-center I set scale factor to 1.5, before the issue happen I checked some gsettings items:
gsettings get org.gnome.desktop.interface text-scaling-factor 1.5 gsettings get com.canonical.Unity.Interface text-scale-factor 1.0 then after several times reboot the issue is reproduced (I guess logout and login will also trigger it), the effect is just like Martin's screenshot. Now the two gsettings items are changed to: gsettings get org.gnome.desktop.interface text-scaling-factor 2.25 gsettings get com.canonical.Unity.Interface text-scale-factor 1.5 I can manually restore it by below command, however the issue still will be reproduced sooner or later. gsettings reset com.canonical.Unity.Interface text-scale-factor -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Sometimes after logging in the text is suddenly much larger than before, and this change persists even after reboot. I was able to get back normal font sizes by modifying text scaling in unity tweak. I'd have to look at this again the next time this happens, but if I understand this correctly then sometimes the scaling factor is re- applied to the text scaling in cases where it was already applied before, thus scaling the text by 1.62*1.62 instead of only 1.62 as it should be.
