Black screen issues on Windows 11 24H2 when ALT+TABing?

fake, this is not solution

Hello guys, found it on Reddit, and its really works for me, i dont have any blackscreens anymore.

I finally managed to fix the Alt+Tab issue, run gpedit and go here:

Computer Configuration > Administrative Templates > Windows Components > Windows Update > Manage updates offered from Windows Update>Enable optional updates

First, change the setting from "no configured to "enabled", then you have to choose the first option (Including CFRs) so you instantly get enabled the gradual rollout features after installing the update.
Uninstall the recent updates including KB5044384 and install them again using windows update after the gpedit modification.

Also, make sure you have enabled fullscreen optimizations. If you disable it, forget about the instant Alt+Tab and HDR while exclusive fullscreen.

I dont think so, you can try disabling Game Mode, change your monitor cable or restore older version of Windows (if you still can).

Good morning, I had same problems and for me reinstall back to Windows 10 was the only solution (couldnt restore older version of Windows 11 because of the timeout on this option). I saw few things like disabling game mode, change your monitor cable so you can definitely try these but personally if its Windows version bug there is not much you can do unless they fix it.

is this fixed for anyone? ive been reading alongside all of you and read the forums, patch notes, release notes... all of it. i still have issues where my system will want to freeze for no reason..
