I’ve tried everything, from running console command FULLSCREEN, to r.FullscreenMode 0, to editing the .ini in /Saved, to creating a DefaultUserSettings.ini in Config. I have literally tried everything I could find in the answer section, and I still get a border when running in fullscreen.
I can’t understand how can everything else be so easily accessible in UE4, yet I can’t get the simplest thing to work. Maybe I’m just an idiot, but I’ve literally edited every .ini I could find. I’m lost.
Edit: I’ve established that this is a bug with UMG, I will repost this question as a bug report.
