Hi all, I have a very strange issue after install any AMD display driver release recently. When I play any games, all in sudden the game will be paused or cannot control like I click alt-tab to switch to other application. I need to manually click alt-tab again to switch back to the game to continue. It seems that some application running in background and auto switch to that app from time to time. This happen when I am browsing internet or using some other application. Does anyone have any idea? Please advise. Thanks!
