The following text line cannot be disabled using the F3 customization menu, unlike all other F3 elements:
Debug charts: [F3+1] Profiler hidden; [F3+2] FPS + TPS hidden; [F3+3] Ping hidden
To edit: press [F3+F6]
This causes unnecessary screen clutter for those that do not want this line, and this line is also massive and put at the bottom of the displayed elements, making this issue that much more apparent.
This issue can be observed by using the F3+F6 customization menu to remove all F3 text elements, while leaving at least one non-text related F3 element enabled (such as the 3D crosshair).
