title: TSC frequency mismatch between VM and host
body: <p>Recently getting this error in Android Studio 3.5, always four times when starting an emulator:</p>
  
  <blockquote>
    <p>4:31 PM   Emulator: <code>qemu-system-x86_64</code>: warning: TSC frequency mismatch between VM (<code>3398030 kHz</code>) and host (<code>3398029 kHz</code>), and TSC scaling unavailable</p>
  </blockquote>
  
  <p><code>ANDROID_EMULATOR_USE_SYSTEM_LIBS=1</code> was already set - and with <code>ANDROID_EMULATOR_USE_SYSTEM_LIBS=0</code> it does not start at all.</p>
  
  <p>What to do about it?</p>
