Description:
When writing text in Writer, the spacings are inconsistent. Sometimes (like in my configuration with the default font), these spacings look a lot like actual space characters, making the text very hard to read, because you see spaces that are not here.

Steps to Reproduce:
1. Open Libre Office Writer
2. Start typing.
3. hope for the bug to happen

Actual Results:
In some cases (in attached file at "dans", second "Kiwi", "immortels", "aimés" second paragraph (twice) there is spacings that split the words. These spaces are roughly the size of a caret (blinking bar).

Expected Results:
I would have expected the spaces to be more consistent. The problem is that they are easily mistaken as spaces, which makes the text hard to read.


Reproducible: Sometimes


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
About reproductibility :
This problem happen consistently accross the same device. When switching to another computer, the problem is still here, but the spaces don't have the same lenght and don't happen at the same place.
Opening the file in Microsoft Word, the problem doesn't show up in word but keeps in Writer.
The problem is independant on the word typed.
I suspect a problem in the rendering engine of the text.
