<pre>I can reliably induce 4x kinject threads soaking up 200% CPU, just by pointing
Firefox or Chrome to Comedy Central's web site (oh the irony) with an external
display attached. The problem never happens if an external display is not
attached. And always happens with the external display is attached.
Also, the system basically becomes unusable. Video playback is jerky, audio
stutters, the whole UI and even the mouse arrow becomes unresponsive.
So I think there's something wrong with the video driver when it comes to
external display support, that then induces the kinject to calm things down,
which then causes the atomic update failure. For sure this is not happening
when I reboot and use Windows 10 with the external display attached.
Is it even remotely plausible the problem is induced by Wayland or Mutter (this
is GNOME)? I could try to reproduce with X. And then try to reproduce with KDE.
I'll reopen it for now so it doesn't get lost.</pre>
