Redshift toggles on and off (flickering)
<p>I installed redshift on ubuntu 16.04 to reduce blue light. However, when I turn it on, it toggles on and off every 1-2 seconds continuously. I ran it in verbose mode (redshift -v) and this is the output:</p>

<pre><code>Temperatures: 3500K at day, 3500K at night
Solar elevations: day above 3.0, night below -6.0

Gamma (Night): 1.000, 1.000, 1.000

</code></pre>

<p>The location is set as well.</p>
