[PyQt] Bug - PyQt 4.4.2 and Matplotlib 0.91.2

[Pierre Raybaut]

Hi,

I found out a performance bug when embedding a Matplotlib 0.91.2 canvas 
in a PyQt 4.4.2 object: the pan/zoom feature is very slow (with PyQt 
4.3.3, and the exact same scripts, pan/zoom is real-time).

I am posting this in Matplotlib mailing-list too, but I thought that 
maybe some of you could have an idea about this?

Thanks for your help!
Regards,
