--- Comment #1 from lkd-fdo at sky-haven.net ---
Additional new wrinkle (old bug but just for completeness)

The monitor I use (Acer XR341CK) evidently has a built-in DisplayPort MST, and
it's controllable for either extending the display or cloning it to the other
DP connector.

All the issues from this bug report disappear provided the MST mode is set to
clone the incoming signal.
