Bug#821046: libvte-2.91-0: Cursor glitch in vim after libvte update

[Yann Hamdaoui]

Package: libvte-2.91-0
Version: 0.44.0-1
Severity: normal

Dear Maintainer,

After the update of libvte from 0.42 to 0.44, I got cursor glitches in vim when
editing files.  When I add spaces at the end of a line, the old blank cursor
is not removed and it leads to the creation of a line of "phantom" cursors.

Here are some screenshots :

There's also a github issues that relates exactly the same problem on arch,
also related to libvte update :
https://github.com/Valloric/YouCompleteMe/issues/2075

The problem is located only in vim, but it does match with the update while
everything works fine on real ttys of the same computer and while everything
else (vim version, vim plugins) haven't changed recently.  The github issue's
poster also state that downgrading to libvte 0.42 solved the problem, I
couldn't try yet a suitable downgrade that doesn't break my system but when I
do I will provide more information.
