[NeVasilek333]

рендерю текст-прямоугольники и тд через wglswapBuffers и они не отображаются

void RenderOverlay(HDC hdc) {
    static int frameCount = 0;
    frameCount++;
    
    if (!hdc) return;
    
    int savedDC = SaveDC(hdc);
    
    SetBkMode(hdc, TRANSPARENT);
    SetROP2(hdc, R2_COPYPEN);
    
    int x = 20;
    int y = 20;
    int width = 200;
    int height = 100;
    int radius = 15;
    
    HBRUSH redBrush = CreateSolidBrush(RGB(255, 0, 0));
    HPEN redPen = CreatePen(PS_SOLID, 2, RGB(255, 0, 0));
    
    HBRUSH oldBrush = (HBRUSH)SelectObject(hdc, redBrush);
    HPEN oldPen = (HPEN)SelectObject(hdc, redPen);
    
    RoundRect(hdc, x, y, x + width, y + height, radius * 2, radius * 2);
    
    SelectObject(hdc, oldPen);
    SelectObject(hdc, oldBrush);
    DeleteObject(redPen);
    DeleteObject(redBrush);
    
    RestoreDC(hdc, savedDC);
}

BOOL WINAPI hkwglSwapBuffers(HDC hdc) {
    static int hookCallCount = 0;
    hookCallCount++;
    
    BOOL result = FALSE;
    __try {

    }

                RenderOverlay(hdc);
