glTexImage2D is not working with excepted

[Dayo]

I want to render image from server so I'm going to use glTexImage2D for render the image.

This is my code for GUI screen in 1.16.5

int texture = -1;

    void initializeGl() {
        texture = glGenTextures();
        glBindTexture(GL_TEXTURE_2D, texture);
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

        glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, 8, 8, 0, GL_RGBA, GL_UNSIGNED_INT_8_8_8_8, myImagePixelArray);

        glBindTexture(GL_TEXTURE_2D, 0);

    }

    @override 
      void render(MatrixStack mat, int mouseX, int mouseY, float partialTicks) {
        if(texture == -1)
            initializeGl();

        glBindTexture(GL_TEXTURE_2D, texture);
        RenderUtil.renderRect(0, 0, 10, 10);
        glBindTexture(GL_TEXTURE_2D, 0);
        super.render(matrixStack, mouseX, mouseY, partialTicks);
    }

Sometimes It works what I excepted but randomly it shows black texture or render only helf. What's wrong with my code?

I cached array so myImagePixelArray always has same data.
