I too expereince system fonts suddenly being displayed at a much lower scaling factor than the 0,9 I have set.
I suspect that this could have happen when I take the laptop in and out of its docking station changing between the laptop screen and a monitor with a higher resolution. Also I observe strange behaviour when I try to reset the scaling factor in gnome-tweak-tool. Usually the scale factor have been set to something like 0.5. Using the plus button to increase the scale factor I observe that the value I set is immediately reduced back to the smaller value without my intervention. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310316 Title: Text scaling factor changing unexpectedly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1310316/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
