Here's a strange problem I discovered after some troubleshooting. Running latest version of Display Fusion on Win 10 and Verizon Messages from the Microsoft Store: https://www.microsoft.com/en-us/p/verizon-messages/9wzdncrdcsnz?activetab=pivot:overviewtab. With the application running but minimized on the taskbar, all seems well -- DF using around 2-3% CPU. But when I open the Verizon Messages window, DF goes to 40-50% CPU -- enough to completely spike it at 100%. If I minimize the Messages window, it immediately drops back to 2-3%. Let me know if you need logs.
