[Elecraft] P3: Enabling SVGA makes display jerky when using narrow span

[Stephen Prior]

I have not noticed this before, and I often reduce the span down to 5kHz or
so when I am calling a DX station spilt.  On both the P3 and the external
1024x768 monitor, instead of a nice smooth waterfall, it is jerky in its
motion and the only setting that I can find to prevent this happening is
the one that disables the external display.

I am running firmware version 1.25.

Any ideas?
