Can’t click on toolbar, menus in Citrix hosted window
 

When a Citrix window is opened on either of the two connected external monitors, they show content correctly, but clicking on anything on the top 1/3 of the Citrix window (that is, in the toolbar, menu bar, or title bar) “clicks through” to the desktop. This started with the display link driver when updated to Sonoma. If I unplug the display link hub so the windows move bac to the MacBooks internal display, I can use the windows just fine, but when I plug the hub (with external monitors) back into the Mac, once I move the Citrixwindow back to either external monitor, the problem returns. Other applications are not affected, it only happens with Citrix, and only after the MacOS update.

If you have not do so already, I would suggest reporting the issue to DisplayLink directly by following the process outlined here --> https://support.displaylink.com/know...to-displaylink
