Linux 4.18+ messages
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.added DC label
This issue hasn't had any activity since 2020-02-28. The AMD driver stack changes rapidly and contains lots of shared code across products so it's possible that it has already been fixed. Please upgrade to a current stable kernel and userspace stack and try again. If you still experience this issue with the latest driver stack, please capture relevant logging and open a new issue referring back to this one.
