Mysterious. I built latest (well almost, since yesterday vim mainline
is a few patches away) Vim 7.3.798 on amd64 architecture on Ubuntu 12.10
and tried to reproduce what you get and still, it seems to work fine.

Here is a screencast, of what I did.

Can you try this please and see, if this triggers the bug for you?
I am starting to wonder, if this could be related to some video driver
bug or so.

regards,
Christian
