It sounds like you are experiencing a common issue related to focus loss on your screen, especially while gaming. When a window loses focus, it can cause interruptions or pauses in your gameplay or activities. Here are a few troubleshooting steps you can try to resolve this issue: 1. Check for Background Applications: - Make sure there are no background applications or notifications stealing focus. Close unnecessary applications running in the background that might be causing the tab to lose focus. 2. Update GPU Drivers: - Ensure your graphics card drivers are up to date. Outdated drivers can sometimes cause such issues. Visit the manufacturer's website to download and install the latest drivers for your GPU. 3. Disable Full-Screen Optimization: - Right-click on the game or application shortcut, go to Properties, and then in the Compatibility tab, check "Disable full-screen optimizations." This can prevent Windows from interfering with the game's full-screen mode. 4. Adjust Power Options: - Sometimes, power settings can cause interruptions. Set your power plan to High Performance to prevent background processes from interrupting the game. 5. Disable Game Bar and Game Mode: - In Windows settings under Gaming, disable the Game Bar and Game Mode. These features might be causing the focus issue. 6. Check Windows Focus Assist: - Ensure that Focus Assist is not enabled. Go to Settings > System > Focus Assist and set it to Off if it's on. 7. Run in Windowed Fullscreen Mode: - If the issue persists in full-screen mode, try running the game in windowed fullscreen mode to see if the problem still occurs. 8. Test in Safe Mode: - To determine if a third-party application is causing the issue, test your game in Safe Mode. Press Windows Key + R, type "msconfig," hit Enter, go to the Boot tab, check Safe Boot, then restart your PC. 9. Perform a Clean Boot: - Temporarily disable all startup programs and services to see if any third-party software is causing the problem. Follow Microsoft's guide on how to perform a clean boot. 10. Check for Malware: - Run a full system scan with your antivirus software to ensure that malware or third-party software is not causing the focus loss. By following these steps, you should be able to troubleshoot the focus loss issue and enhance your gaming experience without interruptions.
