This is triggered by holding Alt and rolling the scrollwheel (or, on a touchpad, moving two fingers vertically).

Since you mention sticky keys: If they are on, the Alt keypress and the scroll event would not even need to occur simultaneously to trigger magnification.

To disable magnification,

  • Using CLI:

    xfconf-query -s false -c xfwm4 -p /general/zoom_desktop
    
  • Using GUI:

    Find Settings Editor in your menu (if you can't, just run xfce4-settings-editor), select the xfwm4 channel and uncheck the zoom_desktop value.

Attribution: Ask Ubuntu: How can I disable Alt-Scroll zoom in XFCE4.

To disable sticky keys,

  • Using CLI:

    xfconf-query -s false -c accessibility -p /StickyKeys
    
  • Using GUI:

    • Accessibility > Keyboard > Use sticky keys; or

    • Find Settings Editor in your menu (if you can't, just run xfce4-settings-editor), select the accessibility channel and uncheck the Sticky_Keys value.
