I saw this issue as well. I upgraded from 7.9.somethingold to 8.1.28, and _almost every single component with a font_ had its Dialog font replaced by that synthetica one, and it meant I could no longer save my windows if I made changes. I, as you said, had to simply edit the font and press OK. Note: my fonts in components still _showed as Dialog_, but if I probed them via script, I saw they were actually the synthetica object. I ended up having to write a script to traverse all components on the page and convert them to the Dialog font, as there were _far_ too many places to fix this in. Interestingly, if I dragged on a new component, it too was affected... I have a feeling this will affect development going forward. I should probably raise a support case > [@SerializationException: Error during serialization for property](https://forum.inductiveautomation.com/t/serializationexception-error-during-serialization-for-property/65220/6): > > v8.1.28 I'm getting the same error Unable to create clean copy of class de.javasoft.plaf.synthetica.ScalableFont I'm not using any fonts other than the mapped "Dialog" font confused I did enable the "Use Condensed Font" after upgrading, maybe this is it??
