More information was requested, but none was given within 4 years, and
I'm therefore closing this bug report.  If this is still an issue,

Hello,

As you can see on http://screencast.com/t/IMMvaK7Hqa, I see weird space
effects (interline is growing or decreasing when de-selecting text) with
the "DejaVu Sans Mono" font on Windows.

You notice as well some white pixels in the vertical bar of the
boxquote'd text.

Best regards,
  Seb
