Crosshair Flashes when casting in first person while using SkyHUD or Less Intrusive HUD (Crosshair is disabled)

[johannesrld]

When Casting a held spell in first person view, if you've disabled the crosshair (in any setting, Skyrims option, LIH option or SkyHUD's option) the crosshair will flash wildly until you've stopped casting, this happens even when everything in the "crosshair" section is turned off
