Windows 10: Suttering when multitasking/alt tabbing after updating W11 to B22621

This is completely new. The only thing that's changed on my system in weeks is me updating Windows. All hardware is well-monitored and healthy. Has anyone experienced a similar problem?

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 option doesn't exist in Settings > Multitasking

I want to disable alt-tab from showing and switching between Microsoft Edge tabs. I know the way to do this is by going to settings > System > Multitasking, then there should be an option to change how alt-tab behaves. However, this option isn't showing for me, and I can't seem to find any solutions on the internet... Please help me, thanks!
