This is the Raspberry Pi screen resolution setting that causes this. Need to set the resolution based on the size of the screen first then play around with other magnification settings as well. I have not spent the time to master the setting, just adjusted the setting to Large Screen.
Maybe need to change the screen resolution in the opposite direction. I have had my system off for a while due to changes, but when I get it running, I may try it out. It is possible the apps need some work in relation to fonts but in the meantime, they appear to be concentrating on device functionailty
Ok, figured it out. If you grab the top or bottom of the EKOS window and drag it larger, it will fix those fields.
Bad news is the window now a bit too big and needs to be dragged below the toolbar, but then half the debug window is below the screen. But it's better than not begin able to edit those fields.
