Created attachment 105855 [details] Edit comment and follow description to reproduce bug. In the attached document, edit the comment in the first cell. Attempt to move the text cursor between t and i of the first world. Now attempt to correct the spelling by inserting a 't' between i and o.
Just to ease the suspense left at the end of the bug description, using a caret to represnt the position of the caret, (*) comment as displayed : competi^ors ate them (*) type "t" (*) result expected : competit^ors ate them (*) result observed : competti^ors ate them This behaviour seems to have been introduced in the ranged covered by the daily dbgutil bibisect. But dE reported seeing this in LibreOffice version 4.2.5.2 release. dE, are you sure about that? I am setting platform to "Linux (All)", where I see the problem. dE, if you see it in a different environment, please set platform "All".

bisection is wrong, because the bug can be reproduced with good: [a5750a3c0c5d3b975a787f844d7ba60db53a765e] 2014-07-13, too. The problem is that caret jumps over "ti" in one step, when you press -> once, it is "logically" after "t". When you press -> once more caret stands still, but the it is after "i".
Bisection did not make much sense in this case, it turned out that eb79c13a809c2edf99042b114ede512ebd4c2273 is the first bad commit commit eb79c13a809c2edf99042b114ede512ebd4c2273 Author: Caolán McNamara <caolanm@redhat.com> Date: Thu Oct 10 10:12:44 2013 +0100 update local font.conf for Calibri/Carlito Cambria/Caladea Change-Id: I9391876f2b09750ad5f44483f489743581948d21 Maybe the substituted font (Carlito) reports wrong metrics to LibreOffice.
@Andras You are exactly right. I should have been more willing to believe the bug description. Then I would not have reported bibisect results which are pure noise, with "good" and "bad" depending on nothing more than how I moved the caret before typing the "t". Desk, meet forehad. @all The comment is in font Calibri, but the combination of LibreOffice and my setup provoke the font control to show mouseover message "Font name. The current font name is not available and will be substituted." When the (substituted?) font displays "ti" with a ligature, the caret as rendered does not move inside the ligature; without a ligature, the bug is not evident. In the buggy version, text within a cell behaves the same way as the comment. For comparison, in a bibisect version where Calc displays the bug, Writer displays the same "... substituted." mouseover for font Calibri, there is a ligature "ti", but the caret happily shows itself within the ligature when it is logically within the ligature. I have rewritten the bug summary in line with my observations here. Improvements welcome, of course. Terry.

The below is the commit at which I see the issue appear. (*1 Comment 5 appears to be a red herring - it's easy to mistake this, but to reproduce properly you have to make sure using the cursor keys that the actual (not visible) position of the cursor is inside the ligature) (*2 The previous suggestion of commit eb79c13a809c2edf99042b114ede512ebd4c2273 perhaps applies if there is an externally packaged Carlito available? The end result is of course the same) Adding Cc: to caolanm@redhat.com; Can you tell if this is our bug or somehow an issue within the font itself? commit bde5e683286096b9255254b28a862e519d57f547 Author: Caolán McNamara <caolanm@redhat.com> Date: Wed Oct 23 14:57:32 2013 +0100 bundle Carlito and Caladea Change-Id: Ibb68ad33764bcbab88e68c35805a00287177a5c8
