I must have missed a command. I was able to configure my packaged game to run full screen at 1920X1080 borderless.
This works when the game itself is loaded. However, during startup the Windows taskbar is still visible at the bottom. E.G. When the startup video from my logo plays, it is still visible. Only until the main menu is loaded it dissapears.
My GameUserSettings.ini looks like this:
[/Script/Engine.GameUserSettings] bUseVSync=False ResolutionSizeX=1920 ResolutionSizeY=1080 LastUserConfirmedResolutionSizeX=1920 LastUserConfirmedResolutionSizeY=1080 WindowPosX=-1 WindowPosY=-1 bUseDesktopResolutionForFullscreen=False FullscreenMode=1 LastConfirmedFullscreenMode=2 Version=5
Is there a line of code I need to add to make the taskbar dissapear from the moment the game goes fullscreen?
