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 ?
