I had the same issue and I solved it encoding the screenshoots in Base64:

windows.each do |window|
    within_window window do
      tmp_screenshot = page.save_screenshot(file_path)
        screenshot = Base64.encode64(File.open(tmp_screenshot, "rb").read)
        embed(screenshot, "image/png", "Screenshot")
    end
end

I hope this help
