I'm using Win11 VisualStudio 2022 sfml2.6.1
My project includes <SFML>&&<SFML-Imgui>&&<openCV>, everything works fine when running in the visual studio.But sth went wrong after I tried to run the exe file Created by Visual Studio  Installer Project.
It says:
Failed to activate OpenGL context:
Warning: The created OpenGL context does not fully meet the settings that were requested
Requested: version = 1.1 ; depth bits = 0 ; stencil bits = 0 ; AA level = 0 ; core = false ; debug = false ; sRGB = false
Created: version = 0.0 ; depth bits = 0 ; stencil bits = 0 ; AA level = 0 ; core = false ; debug = false ; sRGB = false
Failed to activate OpenGL context:
Failed to activate the window's context
Failed to activate OpenGL context:
Failed to activate the window's context
Failed to activate OpenGL context:
Failed to activate the window's context
Failed to activate OpenGL context:

Failed to activate OpenGL context:

.......
The window do come up and the Window's Events are Processed,but there is nothing Shown on the Screen.
I have built other project that includes SFML with Installer Project ,no problem occured .

int main() {
        sf::ContextSettings settings;
        settings.antialiasingLevel = 8;
        sf::RenderWindow window(sf::VideoMode(1240, 800), "Map Maker", sf::Style::Default,settings);
        font.loadFromFile("STXIHEI.TTF");
        sf::Clock deltaClock;
        ImGui::CreateContext();
        ImGui::SFML::Init(window);
        ImGui::StyleColorsLight();
        ImGuiIO& io = ImGui::GetIO(); (void)io;
        io.Fonts->Clear();
        ImFont* Font = io.Fonts->AddFontFromFileTTF("C:\\Windows\\Fonts\\msyh.ttc", 25.0f, NULL, io.Fonts->GetGlyphRangesChineseFull());
        ImGui::SFML::UpdateFontTexture();
        while (window.isOpen()) {
                window.clear(sf::Color::White);
                ImGui::SFML::Update(window, deltaClock.restart());
                sf::Event event;
                while (window.pollEvent(event)) {
                        ImGui::SFML::ProcessEvent(event);
                        if (event.type == sf::Event::Closed)
                                window.close();
                }
                ImGui::SFML::Render(window);
                window.display();
        }
        ImGui::SFML::Shutdown();
        return 0;
}

Not sure what "SFML with Installer Project" is, but it sounds like you end up using different DLLs, which can cause odd problems.

Make sure the necessary DLLs are next to your executable that you try to run.
