title: Ubuntu 20.04: dataframe_image with Chrome: InitializeSandbox() called with multiple threads in process gpu-process
body: <p>I have a python script that creates images (png files) from pandas dataframes. For this, I am using dataframe_image and chrome. This works fine on several machines (windows, mac, raspberry), but when I run it on a Ubuntu 20.04 VPS, I get following warnings:</p>
  <pre><code>[0106/141442.845038:ERROR:sandbox_linux.cc(376)] InitializeSandbox() called with multiple threads in process gpu-process.
  [0106/141443.132682:INFO:headless_shell.cc(653)] Written to file /tmp/tmplobys34z/temp.png.
  </code></pre>
  <p>And 10% of the times, it just fills the memory and crashes (process gets killed).</p>
  <p>I tried configuring selenium, but it doesn't make a difference (still having this gpu warning):</p>
  <pre><code>from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
      
  options = webdriver.ChromeOptions()        
  options.add_argument('--headless')
  options.add_argument('--no-sandbox')
  options.add_argument(&quot;--disable-gpu&quot;)
  browser = webdriver.Chrome('/usr/bin/chromedriver',chrome_options=options)
  </code></pre>
  <p>And running dataframe_image with:</p>
  <pre><code>dfi.export(df,'image.png')
  </code></pre>
