The sine sources are sync'd in your flow graph. There is a block inside
the scope sink that non synchronously drops packets when the display is
not active. The lazy way (this is what I often do :-)) is to use one
complex channel with a float to complex block. I think the right way
might involve removing the gr.copy block from inside the wxgui scope
sink guts.
