Windows 10: Alt tab black screen delay

Hello,Ever since i upgraded to windows 11 24h2 every time i alt tab or press the windows key while in a game my screen flashes black and my mouse lags for around 5 seconds and it is very annoying. sometimes its relatively quick when tabbing in to the game and sometimes the other way around. i have tried doing a clean install on all my drivers using DDU and also disabled fullscreen optimizations. The resolution and screen refresh rate in game matches that of the desktop. i dont know how to get rid off this issue. Maybe this is purely the fault of the new windows update being unstable? are there

:)

CTRL ALT DEL Black Screen

Hi Dan,

Welcome to Microsoft Community.

• Have you installed all pending updates?
• Are you able to log into Desktop?
• Is the issue specific to Ctrl + Alt + Del screen?

Black screen error can occur if the computer is not up to date with all Drivers and Windows updates. Install all pending updates and check if that helps.

Refer the link below and perform the troubleshooting steps suggested and check if that helps
