Re: glTexSubImage2D problem with catalyst version 12.10

I have run into the same problem myself.

I am also using glTexSubImage2D with a pixel unpack buffer, followed by glTexParameteri. The same error, GL_INVALID_OPERATION, is returned by glGetError.

Fortunately, glTexParameteri can easily be called before glTexSubImage2D in my program, so thanks for the suggested workaround.

On the other hand, I found nothing mentioned about such a restriction in the OpenGL documentation. And, as usual, I have seen no such error on NVidia GPUs so far.

Here are the details of my configuration:

Windows 7, 64bit

AMD Radeon HD 7800

Driver Version: 12.104.0.0 - Catalyst 13.4 (3-28-2013)

OpenGL 4.2
