Various display settings configuration numeric fields do not save without explicitly pressing enter or tab which might be confusing

As is shown in the GIF:

Here, the height was automatically removed after I activated it without reboot. As a temporary workaround, I need to switch to a new tab and go back, so I guess it should be a front-end issue.

Well, you need to press ENTER or TAB - when you see the "Invalid resolution (skipped)" text, it means the app will skip adding that resolution.

Btw what macOS version are you running? Interstingly the text in the red/orange box does not seem to appear properly. I am not sure why that is. It should look like this:

UPDATE: Oh, I see, the window is set to be small vertically, that's why the text is compressed and the top menu moved under the traffic lights. I'll increase the minimum height a bit.

Note: just checked the code, actually the field should save value when defocused. For whatever reason however it does not seem to work properly in some instances (the field does not defocus, even though the highlight goes away). The issue I face is that currently SwiftUI (Apple's new UI framework the app uses) does not provide a proper workaround I could use. I can try fixing this by adding an explicit "Update" or "Add" button maybe to avoid confusion, but that feels somewhat clunky. Will investigate this in the future more as I agree that the current way it works is somewhat unintuitive.

I just changed it so the field is submitted after each keypress. That should work (unless the user decides to abandon things midway, that might cause obvious problems).

(separated the menu Settings menu bar stuff to a different issue #3375)

The issue actually affects all other fields similarly so changed the behavior of all.
