Comment 35 for bug 1767312

I hit this bug on Fedora 28 when using a third-party mesa build. Here's the ~/.drirc I used to fix this:

<driconf>
  <device driver="radeonsi">
    <application name="totem" executable="totem">
      <option name="allow_rgb10_configs" value="false" />
    </application>
  </device>
</driconf>

This also fixed the timecode in Totem showing strange, rainbow colors, caused by the same thing. Repeat the application section as required for each program affected.
