C++ 添加转换后对象渲染奇怪

我正在向我的C OpenGL程序添加转换.我正在使用CGLM作为我的数学库.程序没有警告或错误.然而，当我编译和运行程序时，我得到了预期图像的扭曲版本(在添加转换之前它没有扭曲).下面是我的程序的主循环

// Initialize variables for framerate counting
double lastTime = glfwGetTime();
int frameCount = 0;

// Program loop
while (!glfwWindowShouldClose(window)) {
    // Calculate framerate
    double thisTime = glfwGetTime();
    frameCount++;

    // If a second has passed.
    if (thisTime - lastTime >= 1.0) {
        printf("%i FPS\n", frameCount);

        frameCount = 0;
        lastTime = thisTime;
    }

    processInput(window);

    // Clear the window
    glClearColor(0.2f, 0.3f, 0.3f, 1.0f);
    glClear(GL_COLOR_BUFFER_BIT);
        
    // Bind textures on texture units
    glActiveTexture(GL_TEXTURE0);
    glBindTexture(GL_TEXTURE_2D, texture);
    glActiveTexture(GL_TEXTURE1);
    glBindTexture(GL_TEXTURE_2D, texture2);

    // Create transformations
    mat4 transform = {{1.0f}};
    glm_mat4_identity(transform);

    glm_translate(transform, (vec3){0.5f, -0.5f, 0.0f});
    glm_rotate(transform, (float)glfwGetTime(), (vec3){0.0f, 0.0f, 1.0f});

    // Get matrix's uniform location and set matrix
    shaderUse(myShaderPtr);
    GLint transformLoc = glGetUniformLocation(myShaderPtr->shaderID, "transform");
    // mat4 transform;
    glUniformMatrix4fv(transformLoc, 1, GL_FALSE, (float*)transform);

    glBindVertexArray(VAO);
    glDrawElements(GL_TRIANGLES, 6, GL_UNSIGNED_INT, 0);

    glfwSwapBuffers(window); // Swap the front and back buffers
    glfwPollEvents(); // Check for events (mouse movement, mouse click, keyboard press, keyboard release etc.)
}

如果您想查看完整代码，该程序位于github here上.

The Output of the program is this (The square also rotates):

However, the intended output of the program is the penguin at 20% opacity on top and the box at 100% opacity underneath the penguin.

提前感谢您的帮助.
