Hi Chris, in my experience it can literally happen to any document I use
in LO. So even a new document I just started with only default
formatting. So if there's any consistency in it, then it probably has to
do with my system configuration or the way my system creates document
and then interacts with my graphics driver.

So I attached an example .odp-slide that I use regularly to maybe give
you a clue. Any suggestion / help is welcome. Again: I do realise that
this is becoming quite a particular bug (hard to reproduce, potentially
related to my system configuration). So I understand if you want to give
up on it at any point.

** Attachment added: "Document that I use often that regularly gives problems. However, note that problems can occur with *any* LO-document I use, even new ones with only text in default formatting."

Title:
  LibreOffice has serious kerning issues with characters' display of
  font, bold, italic

Status in xorg package in Ubuntu:
  Expired

Bug description:
  I run in to distorted text in LibreOffice, depending on zoom level. At
  first I thought it was a LO-bug, but now I have found that I don't get
  this issues when I run the AMD proprietary driver (fglrx). So I think
  it might be a problem in the xserver-xorg-video-ati driver. I have a
  Radeon HD 8600M series in a Lenovo S540.

  The attached file shows an example of the bug that I had in Calc. The
  bottom right is the 'normal' text. Three lines, with the bottom one in
  bold. Depending on the zoom level, the text is distorted in many ways:
  bold / italic / font (appearance).

  Some extra information:
  -This happens in all LO-apps I use: Calc, Writer, Impress.
  -I don't have a clear way of reproducing it. The apps normally start out perfectly fine. After a while this can happen, not always. Risk factors seem to include having multiple LO-files open, especially between different apps.
  -It is not always that the 100% zoom level is ok. That can be distorted too.
  -This never ever happens in any other app / program I use.

  If this is unlikely to be caused by the xserver-xorg-video-ati driver,
  I apologize for reporting it here. If you need additional information,
  please let me know, I will be happy to provide.

  Required info:
  1) Ubuntu 14.04.2 LTS
  2) xserver-xorg-video-ati Installed: 1:7.3.0-1ubuntu3.1
