I am runnign LM14 Cinnamon with Cinnamon 1.6
Often when I cange a setting, the panel Icons (seen in image below) change to a MASSIVE size. I am unsure how to remedy this appart from putting all settings back to default.
(Look in top right and bottom right)
In this instance, I changes the Font scaling from 1.0 to 0.9, and then the Icons became huge.
It has also happened after a system restart.
