Resolving screen flashing issues on Windows 10

If you are experiencing screen flashing issues on Windows 10, there are a few steps you can take to resolve the problem. The first step is to check for any available updates for your operating system and install them. Restart your computer and see if the issue persists. If it does, try starting your computer in Safe Mode to see if the problem is caused by a third-party software.
If the issue is resolved in Safe Mode, it may indicate that a recently installed program or driver is causing the problem. You can try uninstalling any recently installed software or updating your device drivers. If the screen flashing occurs only when using a specific application, try running it in compatibility mode or updating the application to the latest version. If none of these steps resolve the issue, you can try resetting your PC or performing a clean installation of Windows 10.

        Thread flashingThread = new Thread(StartFlashing);

        flashingThread.Start();
        // Continue with the rest of your application's startup logic

        Console.WriteLine("Startup logic continues...");
        // Wait for the flashing thread to finish (optional)

        flashingThread.Join();
        Console.WriteLine("Application execution completed.");

    }
    static void StartFlashing()

    {

        // Retrieve the handle of the console window

        IntPtr consoleHandle = GetConsoleWindow();

// Flash the console window for 10 seconds const int flashDuration = 10000; // 10 seconds DateTime endTime = DateTime.Now.AddMilliseconds(flashDuration); while (DateTime.Now < endTime) { FlashWindow(consoleHandle, true); Thread.Sleep(500); // Flash every half second FlashWindow(consoleHandle, false); Thread.Sleep(500); } } [DllImport("kernel32.dll")] public static extern IntPtr GetConsoleWindow(); }

This code uses the `FlashWindow` function from the Windows API to flash the console window at regular intervals. However, please note that this is just a basic example and may not work as expected on all systems or in different contexts.
