The font looks 14 point and is reported as 14 point under Preferences > Display > Colors and Fonts. Fully exiting DOpus and restarting has no effect - the unwanted font size persists.
If I right click on the Desktop > Screen Resolution > Make text and other items larger or smaller > and change the scaling factor - the system asks you to sign out and re-sign back in to complete all the setting changes. After I do that, there are the unwanted font sizes. As mentioned, the font settings within DOpus will have changed. I have to manually go back into the Preferences > Display > .... and reset them from 14 point to 10 point. Given that there a lot of font settings - it's a huge pain.
If DOpus would just internally respect my previously specified (10 point) font setting and not change on it's own, I'd certainly appreciate it!
