So as my topic title says, I alt+tab to the proper window that I want to go to, which works but I need to do an extra left click to fully go in and make the alt tab window choices disappear. I closed display fusion to verify if it was an issue from windows 10 but it alt-tabs properly when display fusion is closed which leads me to believe it's an issue with display fusion.

I took a screenshot of an example of the issue, at the moment where I took the screenshot alt+tab were not pressed anymore.
