When some programs are opened, they do not show up in the Alt+Tab menu as a program I can tab into. I have to manually click on it in the taskbar to bring the program back into focus. Not all programs running in borderless windowed do this as some show up normally.

I've noticed this happening with Windows Movies & TV and Call of Duty Modern Warfare 2019. For Windows Movies & TV, it will show up initially in the Alt+Tab menu when opening a video file. When switching to a different tab, it disappears from the Alt+Tab menu unless I double click the video player to leave the fullscreen mode. Call of Duty Modern Warfare runs in borderless windowed mode without any third party programs.

When the DisplayFusion Alt+Teb is disabled, the default Windows Alt+Tab menu does not have these issues and displays all programs normally. I haven't changed any of the Alt+Tab advanced settings. I'm using Windows 11.
