screen saver="warp" not working

[Ernie Luzar]

Hello list,

Since FreeBSD 7.0 I have been using the screen saver enabled in rc.conf
saver="warp"
Now in 11.0 with vt as the default console drive having so many problems 
I have opted for using kern.vty=sc in /boot/loader.conf. Now the warp 
screen saver just shows a black screen with no stars fly past.

Is this another unknown problem with the vt?

Thanks
