- Electron version: 1.3.7
- Operating system: macOS & Windows

I'm having some trouble creating a minimal repro for this but it seems that the `ready-to-show` event is not firing for us, since ~1.3.7, despite us having `show: false` in the window options. Filing this in case others are seeing the same behavior.

We had to switch to using `browserWindow.webContents.on('dom-ready', ...`).

  if (!window()->transparent())
    return;
  content::RenderWidgetHostImpl* impl = content::RenderWidgetHostImpl::FromID(
      render_view_host->GetProcess()->GetID(),
      render_view_host->GetRoutingID());
  if (impl)
    impl->owner_delegate()->SetBackgroundOpaque(false);
}
void BrowserWindow::DidFirstVisuallyNonEmptyPaint() {
  if (window()->IsVisible())
    return;
  
  
  auto* const view = web_contents()->GetRenderWidgetHostView();
  view->Show();
  view->SetSize(window()->GetContentSize());

                         self->Emit("ready-to-show");
                     },
