Some programs try to get smart and do things when they detect they are in borderless full screen mode. In my experiences, these things are usually detrimental. This tweak will set the pixels off by one, which can avoid this in the cases I saw. If the programs you are using behave fine without this tweak, maybe keep it off to get a bit closer to pixel perfection.

  When enabled, borderless full screen will not attempt to remove the borders, but instead will try size the program in such a way that the borders would be outside of your screen. Some programs try to fight the normal mode, but will work with this enabled.

  Span all screens when using the borderless full screen feature.

  When switching to borderless full screen, attempt to overscan/underscan horizontally by this ratio. Some programs may resist overscan, but underscan should work more often.

  When switching to borderless full screen, attempt to overscan/underscan vertically by this ratio. Some programs may resist overscan, but underscan should work more often.

  This number of pixels will be cut off from the top of the borderless full screen window. This is useful if there is some kind of menu that you would like to hide.

  When enabled, programs that have been set to borderless full screen will automatically reset to full screen if changed. This is helpful for some applications which change their sizes and positions for strange reasons. You will need to toggle the borderless full screen off for it to unlock.
