Windows 10: Computer freezes whenever exiting or alt+tabbing a fullscreen game

the games themselves run completely fine, no issues, but whenever i switch tabs or exit to desktop, my entire computer freezes, and i have to restart it. This happens mostly with csgo, valorant, and r6 siege, which are games i happen to play alot, and its really annoying to have to restart whenever i stop playing. i did just download valorant recently, and that was around the time this problem started happening, however i can remember it happening once or twice before i downloaded valorant. so if me downloading valorant has anything with it, lmk. any fixes?

Weird alt-tab out of fullscreen games.

Hi Simon,

The multitasking capability of a game depends on the total memory of your computer. If you have large amounts of RAM on your computer, it can multitask heavy programs easily like high-end games. To ensure that we can provide the appropriate resolution
for your concerns with the alt-tab function, we’d like to ask you a few questions:

• What were the recent changes made on your computer before you experienced this issue?
• When did the issue start?

• Have you pressed the alt-tab key during you play Rainbow Six Siege? Or it just happen without pressing it?
  
• Does the automatic ALT-TAB behavior happens on other games?
• Do you have any other programs running on your computer while playing?
• What is the anti-virus program you're using?

• What is your device or system specifications? To know, follow these steps:
  1. Press Windows + S and type
     About your PC.
  2. Send us the information listed under Device specifications.
  
  

Moving forward, if you're multitasking while playing, we recommend that you play this game only without doing other tasks. Pressing ALT-TAB or performing a multitasking interferes with the performance of your video card, especially if you're running a heavy
game like Rainbow Six Siege. It will generate screen viewing issues like intermittently switching your game screen between your desktop environment.

For now, restart your game and do not press ALT+TAB while playing. This will allow your video card to dedicate its graphics performance on the game only instead of your desktop environment.

If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.

 

alt + tab not working

Just found a really cool way to make alt+tab INSTANT!!!

In the launch options write the following: -windowed -noborder





This play exactly the same as fullscreen but now you dont have to wait 30 f*@!ing seconds to alt+tab back in!

Also you don't get the little purple/black checkered effect (only in Source games) from alt+tabbing in fullscreen.

 

Black Screen issue for Exclusive Fullscreen mode when exiting or Alt+Tab to Desktop after Anniversary Update

Hello, Pavan, I would like to add a few more details to this issue.

This seems to be an issue for multiple games running on exclusive fullscreen mode. Happens with Child of Light, Rocksmith, The Witcher, Resident Evil Revelations, World of Warships and a few others from what I could see. They all share the
same circumstances, and the only way to avoid this issue is to set the game to run on borderless fullscreen mode.

When stuck in this black screen, the only way out is to press ctrl+alt+del, and blindly go to the "change user" option ("down" and "enter" after pressing the combo). After logging back into Windows, the issue is gone. Another way of avoiding this issue is
to alt+tab from the game, exit it from the taskbar or forcefully killing the process.

I would like to say that this is a problem related only to Windows 10 Anniversary Update. This issue never happened before on previous Windows 10 builds and the reproduction rate of this issue is 100%. If you have an affected machine, this is going to happen
every time you exit an affected game. This seems to happen only to a handful of games, so keep that in mind.

Hopefully you can address this issue as soon as possible, because it is very frustrating.
