Description:
After upgrading to the 5.3 series, I found that the spacing between characters is slightly different than the 5.2 series and previous. This messes up the formatting of documents. I found the issue with Times New Roman, at least; it cannot be replicated with every font but there could be others. It is perhaps worth nothing that Liberation Serif (made to be metrically identical to Times New Roman) is identical in all versions of LibreOffice and uses the same space as Times New Roman in the 5.2 series and before, so the problem is with the 5.3 series. I'm using Ubuntu 16.04.

Steps to Reproduce:
1. Make a document with Times New Roman as the font.
2. Open it in LibreOffice 5.3.
3. Compare its formatting and character spacing to LibreOffice 5.2.

Actual Results:  
Because the spacing is slightly different, the page looks different than in older versions of LibreOffice, which can mess up formatting.

Expected Results:
The document should look identical across versions of LibreOffice. 


Reproducible: Always
