UPDATE: I tried adding a second navbar to the right (don’t ask me why) and it solved the issue. But I cannot keep the 2 navbars… maybe this can help find out why it’s not displaying properly.
I believe what you want to try is adding is a rectangle object that fills the rest of the screen but is a 0% opacity background. This may help to keep the object from resizing for the screen.
It takes a lot of messing with things to get a layout to work. Would be really great if someone who understands the ruleset their rendering uses could teach us the basics in a video. It’s using something akin to the CSS box model but with a bunch of corollaries I don’t understand.
