Outlook selections not visible.

[AllanT]

I am having some trouble with Outlook while using DisplayLink. When looking at my Inbox, the highlight that shows which message is currently active is not visible. What's strange is that if I take a screenshot and disconnect from DisplayLink the highlight becomes visible in the screenshot:

I am assuming this has something to do with the colour depth, but I haven't been able to find it. Any assistance would be appreciated.

The system is as follows:
MacBook Pro 14" M3
USBC-6960M DisplayLink adapter
2x Samsung LU28R550UQNXZA
DisplayLink Manager 1.10.1 (Build 93)
