Sorry I have not been able to look at this today. I have had family things on.
Thanks for looking into that. I half suspected that might be the case. So after
everything I said about contracts with the Show function, it seems it is
already broken ☹
I suspect that actually this is a wxWidgets bug. But the documentation around
Create is sparse. Probably we should generate a minimal example and report it
to wxWidgets.

Subject: Re: [Plplot-devel] Infinite Yielding issue
@Phil
it seems the problem on the code in the current master is that the Yield(0
is called before Show()
if I change to after Show(), like this, I get the result below
wxPLplotwindow<wxFrame> *frame = new wxPlDemoFrame();
frame->Create( NULL, wxID_ANY, wxT( "wxPLplotDemo" ) );
PLPLOT_wxLogDebug("frame->Create");
frame->SetIcon( wxIcon( graph ) );
frame->Show();
//We must wait for the Create event to be processed and the
//wxPLplotstream to be prepared
while (!frame->IsReady())
{
PLPLOT_wxLogDebug("Plot() Yielding");
wxGetApp().Yield();
}
//Now we can set up our frame and do the plotting
Plot( frame );
