UPDATE: I discovered what's going on, sort of...

If I press Alt, it toggles this behavior, with the yellow diagonal lines/red BG control-names
It might be a debugging behavior, but it was a bit of a surprise. (When I press Alt in my own app (https://gitlab.com/sjsepan/VLangApp1) there is a little red outlining on the lone button, but that is all.)

I'll let you comment and close if you see no problem. It's just that I did not notice anything in the iUI readme about this.
