    bug with large image ( more than 2048 ), glTexImage2D and GL_BGR image format on AMD ATI FirePro v4900



      i have a graphic card AMD ATI Fire Pro V 4900 (window 7 x64) and would like upload an image (6Kx6K) with GL_BGR or GL_RGB pixel format into a 2D Texture (i'm using a pbo to transfer data to gpu). When i try to call glTexImage2D, application blocks indefinitely. Can you help me to understand if there is a driver bug?

      I tested the same application on different Nvidia graphic cards with good results.

      Thank you
