The issue of black shadows left behind by apps when closed or notifications dismissed can be related to various factors. It could be a bug in the app itself, a graphics driver problem, or an issue with the operating system's graphical user interface. Here are some troubleshooting steps to help you resolve the problem:
Update the app and OS: Make sure you have the latest updates installed for both the problematic app and your operating system. Developers frequently release updates to fix bugs and improve app performance.
Restart the app or device: Sometimes, the issue can be temporary, and restarting the app or your device might resolve it.
Check for driver updates: Ensure that your graphics drivers are up to date. Outdated or corrupted graphics drivers can cause various graphical issues. Visit the website of your graphics card manufacturer to download and install the latest drivers.
Adjust graphics settings: Experiment with different graphics settings in your operating system. Try changing the resolution, refresh rate, or color settings to see if it makes any difference.
Test with a different user account: Create a new user account on your device and see if the issue persists there. If the problem doesn't occur in the new account, it might be related to user-specific settings or configurations.
Disable hardware acceleration: Some applications use hardware acceleration to improve performance, but it can sometimes lead to graphical glitches. Try disabling hardware acceleration in the problematic app's settings (if available) or in your system settings.
Check for third-party conflicts: If you have recently installed any third-party apps or software, they might be conflicting with the display settings. Try uninstalling recently added software and check if the issue is resolved.
Scan for malware: Malware can cause unexpected behavior in apps and on the system. Run a full system scan using a reputable antivirus or anti-malware program.
Check for known issues: Look for any known issues or bug reports related to the specific app or your operating system. Online forums and community websites can be helpful in finding such information.
Report the issue: If you cannot find a solution, consider reporting the problem to the app's developer or the operating system manufacturer. They might be able to provide additional assistance or include a fix in future updates
