Using the tiled/MST monitor Dell UP3214Q connected over DisplayPort with the
MSI B350M MORTAR (MS-7A37) with the Raven device Ryzen 3 2200G causes problems
when switching the inputs of the monitor (two systems are connected).
I believe the monitor firmware is buggy, but the problems do not happen with
Microsoft Windows.

Here is a verbose log. I believe it’s related to DP 1.2 and the MST Dell
monitor.

Hi Paul, can you please explain what you did by "when switching the inputs of
the monitor (two systems are connected)"?

The monitor has several inputs. Over the OSD (on-screen display) you can tell
the monitor what input signal it should display (or the monitor auto-senses it
itself). Hopefully, that makes sense.

Thank you. You connect both HDMI and DP to UP3214 with DP1.2 enabled, switch
back and forth, and the warning is showing up. When the warning is observed, a
delay is also observed. Am I right?

Can you clarify the problem you're observing?
Do all the displays go blank after switching inputs?
