OpenCV 2.2 window causes problem on OpenGL (Bug #1147)

Here is very simple code .. Only thing is I repeated same code manytimes for detail debug. Detail info: OpenGL version 3.3.0, Window 7 OS and VS2008, OpenCV 2.2.0.

 1//*********************************************
 2RenderObject();
 3//glPushClientAttrib(GL_CLIENT_ALL_ATTRIB_BITS);
 4Mat image;
 5image.create(screenHeight,screenWidth, CV_8UC3);
 6glReadPixels(0, 0, screenWidth, screenHeight, GL_BGR, GL_UNSIGNED_BYTE, (uchar*)image.data);
 7int error_code1 = glGetError();  // Error Code: 0, NO Error, Also output is good/as expected!
 8glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, 0);
 9int error_code8 = glGetError();  // Error Code: 0, NO Error
10//flip(image, image, 0);
11//glPopClientAttrib();
12const char *title = "glReadPixels Output";
13cv::namedWindow(title);  
14int error_code2 = glGetError();  // Error Code: 1282, GL_INVALID_OPERATION
15imshow(title, image);
16int error_code3 = glGetError();  // Error Code: 1282, GL_INVALID_OPERATION
17waitKey(5000);
18int error_code4 = glGetError();  // Error Code: 0, NO Error
19destroyWindow(title);
20int error_code5 = glGetError();  // Error Code: 1282, GL_INVALID_OPERATION
21image.release();
22
23int error_code6 = glGetError();  // Error Code: 1282, GL_INVALID_OPERATION
24
25glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, fboId);
26glDrawBuffer(GL_COLOR_ATTACHMENT0_EXT);
27glReadBuffer(GL_COLOR_ATTACHMENT0_EXT);
28
29int error_code7 = glGetError();  // Error Code: 1282, GL_INVALID_OPERATION
30//*********************************************

Something going on here under-the-hood. What is that? ... well at least error_code7 should be 0 (i.e. no error) even if OpenCV window is taking over the default buffer. I tested code with framebuffer object as well as default glut hidden window. Also let me tell you that I must use framebuffer object for my purpose. So, cannt use same default window to draw and show.
