GUI Scale can be set to -1

Pressing the Ctrl key when the GUI Scale is set to Auto while scrolling the mouse can change the GUI Scale to a negative value in the Video Settings menu.

The Issue:

When scrolling the mouse wheel from downward, the GUI Scale value is set to -1.
It is purely visual as it does not affect the way the screen is rendered and come back to normal when leaving and returning to the screen again

How to reproduce:

• Set the GUI Scale to Auto
• Scroll downwards with the mouse wheel
• Observe that the GUI Scale has been set to -1
