NSOpenGLView and ATIR128Pro OpenGL Driver

After having let a project rest for a while since Mac OS X 10.0, I got back working on it yesterday and discovered a problem with the NSOpenGLView while using the ATIR128Pro renderer.

I don't know whether it's coming from the ATI renderer or the NSOpenGLView code or the OpenGL code (whose Software renderer doesn't support Z-Buffer currently), but it seems something got broken between 10.0 and 10.0.2 . When I resize a NSOpenGLView (yes, I have a reshape method), the drawing is buggy. It seems there is an offset in the way the image is blitted to the screen.

Instead of having a vertical line rendered like it should:

I have this

I made some tests to see if I was not doing something stupid with the OpenGL call but since the rendering is perfect (except for Z-Buffer) with the Software renderer, I'm thinking it's a bug but I don't know the culprit (NSOpenGLView, OpenGL, ATI Driver).

Is it a known problem or should I fill a bug report ?
