Using gVim on Win XP, italic characters are cut on the right when they
are highlighted.

In attached screenshot, gVim highlights all characters in the same
column. When moving from left to right, all italic characters in another
line are cut off. After being highlighted the characters stays with
missing pixels until you switch windows.

Tested with other fonts and couldn't reproduce with Consolas, Deja Vu
Mono, Droid Sans Mono. This happens even when Cleartype is off.

I couldn't trigger this bug in others text editors so these are the
steps to reproduce in gVim. You can download it at
http://www.vim.org/download.php#pc

Included themes does not use italic characters by default so you should
install solarized for gvim from https://github.com/altercation/vim-
colors-solarized to make this easier to trigger

Once you have installed the app and the theme and installed Ubuntu Mono
in the system, open up gVim and begin typing:

:set guifont=Ubuntu_Mono:h13
:colorscheme solarized
:set cursorcolumn

Press i to enter insert mode and type in the file:
<!doctype html>
Lorem ipsum dolor sit amet

Now you can use the toolbar or menu to save the file. Save it with a
.html extension.

Press Esc to leave insert mode. Now click at the beggining of the second line.
Start pressing l (lowercase L) to start moving to the right.
Now you should notice that the characters in the first line are cut off on its right side.

Also notice that this does not happen when moving from right to left.
