           Summary: Cursor behaviour with Graphite fonts
           Product: LibreOffice
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libreoffice
        AssignedTo: libreoffice-bugs at lists.freedesktop.org
        ReportedBy: rgbl at email.it


Steps to reproduce the problem:
1- Install Linux Libertine G font from here: http://numbertext.org/linux/
2- Open a Writer document and type the following text

Some text \prime Some text fi more text

3- Modify the paragraph style to use the Linux Libertine G font with "tex mode"
enablesd (on the font name box type: Linux Libertine G:texm=1)
"\prime" will change into ' and fi will be replaced with proper typographical
ligature.
4- Put the cursor on the end of the paragraph and use the cursor arrows to go
to the left one character at a time.

Actual result:
While the cursor behaviour is OK on the fi ligature (and this is an improvement
respect OOo 3.2.x), when you arrive to the "prime" the cursor will jump to the
right, possible going to the position where the text \prime should be if "tex
mode" were not enabled.

This behaviour is confusing because the cursor jump to a text position, but if
you press "back space" the text deleted is the one "hidden" by the Graphite
replacement, not the one where cursor is shown.
