Game alt tabbing itself constantly

Hi there.

Whenever I play games on Origin or Origin games with Steam link, the game is alt tabbing itself. Also, I made a quick research on your forum and saw some threads in 2015. Finally, I found a troubleshooting steps at Link and followed these steps but the issue persists still. This is a really annoying issue especially in online games. Can you please help me to fix it? It's really frustrating that issue still persistent since 2015 though. Thanks.
