Can you trying using the "Prevent Window Deactivation" function, and see if the issue persists?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/mouse-not-responding-fullscreen-application/?ID=7a11e2a5-1170-456d-83f3-14fe53ee9449 Fri, 22 Jan 2021 23:21:38 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mouse-not-responding-fullscreen-application/?ID=7a11e2a5-1170-456d-83f3-14fe53ee9449 DisplayFusion Hello everyone,

When I alt tab out of my full screen application on my main monitor (game called Valorant) and I alt tab back into the game, my mouse won't respond to anything in game. It's like the application isn't truly full screen.

It's kind of hard to explain, I tried searching on the forum for someone with a similar issue, but I could not find it.

I do want to run my game in true full screen mode, not borderless window.

Hope you guys can help me out! Thanks! ]]>
