<pre>I've tested some more kernels, all from
<a href="https://kernel.ubuntu.com/~kernel-ppa/mainline/">https://kernel.ubuntu.com/~kernel-ppa/mainline/</a>.
Setting amdgpu.dc=1 on 4.15.18 and 4.16.18 does not reproduce the problem. It
does, however, reproduce on 4.17.19.
Also, I now believe my HDMI monitor may have polling, as it cycles through each
input once when it no longer detects a signal.
Please let me know if there is anything else I can help with.</pre>
