title: Python: selenium-chromedriver error on new browser object
body: <p>I am receiving the below error upon opening a new chromedriver object. The tests run successfully, but this error shows up in our UnitTest output and is undesirable. I would like to either resolve the error or hide it, if possible.</p>
  
  <p>I feel it is important to mention that this output only shows up when running the script from the Windows terminal, not when run from the Python Console.</p>
  
  <pre><code>[0406/170246.792:ERROR:child_thread_impl.cc(762)] Request for unknown Channel-associated interface: ui::mojom::GpuMain

  <p>chromedriver_test.py:</p>
  
  <pre><code>from selenium import webdriver
  
  webdriver.Chrome()

  <p>I have tried </p>
  
  <pre><code>service_args=["--silent", "--log-level=0", --"disable-extensions", --"log-path=/PATH/TO/LOGS"]
  </code></pre>
  
  <p>also:</p>
  
  <pre><code>sys.stdout = open(os.devnull, 'w')
  sys.stderr = open(os.devnull, 'w')

  <p>I have also tried redirecting the output to NUL</p>
  
  <p><code>$ python chromedriver_test.py &gt; NUL</code></p>
