OpenShell Menu and DisplayFusion on Win10 Taskbars are different colors

[major4579]

I'm running the latest version of Open-Shell Menu (4.4.196) and the latest version of DisplayFusion Pro (11.2) on Windows 10 (22H2). My taskbar on the primary monitor is in the accent color I picked, but the taskbar on the secondary monitor is black. I contacted DisplayFusion and they had me try some things without any luck. The latest request was to disable Open-Shell Menu and reboot, which I did - and that 'cured' the problem, i.e., both taskbars were in the accent color. So the immediate reaction is that Open-Shell Menu is the cause (maybe, maybe not).
In DisplayFusion I have Multi-Monitor Taskbars enabled, and my mode is "All taskbars show relevant windows".
Any thoughts?
Thanks.
