<pre>I am seeing a similar issue on an X1 4th Gen and using a dock with two attached
monitors (DP). It seemed to be somewhat worse if one of the monitors has MST
enabled (DP 1.2 switch). This was also on GNOME (Fedora 29, Kernel
4.18.13-300.fc29, mutter 3.30.1-2.fc29).
What works for me as a workaround is avoiding the "hotplug" by suspending the
machine and then resuming it again after plugging in the monitors. Unplugging
generally worked fine for me.
I'll do a local build of drm-tip and see what happens there.</pre>
