Created attachment 83221 [details] the font "Rotis Semi Sans 55" LO 4.1.0.4 on Ubuntu 12.04 64bit After updating from LO 4.0.2.2 to 4.1.0.4 documents written with the font "Rotis Semi Sans 55" (a special font from my company, that I have to use in many documents) aren't displayed correctly anymore. The distances between the paragraphs are too small. In 4.0.2.2 documents with this font worked without problems. If I open a new document and change the font to "Rotis ..." and start writing the paragraph distance is too small. All other fonts are working normal. This is a very severe problem for me, because all people in my company have to use this font for official documents. In the attachment you can find the affected font for testing.
In my bug report before I forgot something. If I change the font for example in Arial Narrow, which is quite similar, the document is displayed in a normal way and the distances between the lines are normal.
Today I saw that impress shows the same behaviour. If I open a presentation with the font "Rotis..." the line height is too small. I think LO displays the signs not in the real height. I will add screenshots of the page in "Rotis" an the same page in "Arial narrow".

Created attachment 83564 [details] FontForge screenshot of metrics for Rotis and DejaVu Sans fonts. This is not necessarily the cause of the problem, but it is worth noting that the SPACE (U+0020, named "glyph1") character in the provided custom font is mapped to the beginning of the Private Use Area (U+E001, named "space"). I am not sure why this would be necessary, but it seems erroneous. A more likely cause of your problem is that LO is now (more) correctly interpreting the metrics of your font. I have attached a screenshot of what FontForge shows for the OS/2 > Metrics tab. There are significant differences e.g., a "Typo Line Gap" of zero for your font. It is possible this is contributing to the line spacing issue.
Today I tested LO 4.1.0 on Windows XP and here the font "Rotis Semi Sans" is displayed in the right way. So I think it's only a problem on linux machines.
After upgrading to 4.1.1.2 the problem still exists.
After upgrading to 4.1.2.3 the problem still exists.
After upgrading to 4.2.0.4 the problem still exists.
After upgrading to 4.3.1.2 the problem still exists. OpenOffice 4.1.0 on the same machine displays the font correctly.
