I can obtain a (perhaps slightly different) freezing too.

It's definitely a real bug. I can currently reproduce it very well 
(altogether with
some other buggy behaviours I just discovered right now ;-(... ). I 
don't need
more info to start tracking these bugs. It seems the problem is somewhere
in the rendering engine, thus it could take time to understand exactly
what's happening, it's not just simply that some limit condition has
been forgotten... But in any case, this problem must be corrected,
thank you very much for having reported it. I will try to fix this
soon, i.e. during the next weeks.
