When i am using this while i play apex legends fullscreen the game is not going back to its screen and i have to close display fusion in order to work
but when i add in compatibility to force as full screen option and disable hooks still the issue persists
so i have to select close taskbars when game is open but that doesnt work
moreover the prevent window deactivation is not working with apex legends as soon as i use chrome on other monitor it minimizes.

See and more over whenever i try to use apex legends the taskbars start bugging out and removes all the pinned taskbars and refreshes that

Hey done that settings but the alt tab is taking too much time and my screens flash black and 5-10 sec lag happens

yea did that but still alt tab is taking ages and computer all screens freezes black and lag

checking with single display also with display fusion on it still does that check https://clips.twitch.tv/ApatheticPuzzledCookieDBstyle-BKNzRElCLil1t__d
in this i have 2 monitors cloned only so single screen basically and still it happens but when i close it doesnt happen.

Nah man its still like 5-6 seconds of black screen on my monitors

Hey i am using the latest stable version not beta version for your information.
i am using 9.9 version available on steam.

Hey i updated but taskbar goes off when i alt tab to desktop and then alt tab back in game it stays black for 3-5 seconds could you check the log
its still the same problem.

Well to be honest i only play apex
i think to reproduce this you need 3 monitors or 2 monitors +1 capture card like me
i have cloned 2 monitors primary 240hz with capture card but this error also occurs when cloned to other display also
then the alt tab delay becomes very bad and after quitting the display fusion it comes back to normal

well i tried extending the capture card and now it's working fine again.
so yes this happens when i clone my primary monitor to capture card scenario to me.

also prevent game window to minimise is not working with apex legends. can you check.
So if i want to use chrome on other screen it gets minimized can you fix that too

Let me know if anything you do to fix it in any new beta update for me to check
