glCopyTexImage2D() that goes "clipped"

Hi,

I've noticed a quite annoying problem with glCopyTexImage2D() inside a 
windowed GL context (not fullscreen).
If you use the current frame buffer for some copy to texture, the 
texture goes clipped with white pixels when
the window doesn't fit on the screen or is minimised.  This only happens 
on ATI drivers as far as I've noticed.

The solution would be to use an independent pbuffer but I'm wondering if 
it exists some alternatives.

Thanks before hand,

Igor.
