I have widgets that sit on the edges of the viewport that show the location of actors that are off screen. When I play in the main viewport (the active level editor viewport), these markers are not visible. If I play in a new editor window (for example, playing while looking at an event graph), they show correctly. These marker widgets are placed and moved based on the viewport size (get viewport size) and the targets screen location (project world to screen).
I suspect its a settings problem with the level editor window and that it will not affect a packaged build. Its more of an annoyance really, but I would like to know what is going on and how to fix it. Any ideas?
