<pre>Summary: I'm seeing a very brief screen flicker, uncertain of the interval
(perhaps once per half hour), whether using built-in only display or external
(appears on both displays). This is a regression, it doesn't happen with
4.18.x.
model name : Intel(R) Core(TM) i7-6500U CPU @ 2.50GHz
00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics
520] (rev 07)
I've enabled drm.debug=0x1e but can only isolate to about 1 minute (I see the
flicker, look at the time, and then use journalctl --since= to capture from the
start of that minute.</pre>
