Text displayed correctly at 90 % zoom level

Steps to reproduce:

- Enter a text consisting of multiple lines (Ctrl-Enter) into a cell.

- Choose various zoom levels to experience one of the following symptoms,
  reproducibly dependent on the zoom level:
  - Text gets displayed correctly, i.e. fits perfectly into cell, or
  - there is additional space below the last line, or
  - the last line gets cut, or
  - the last line is invisible


Additional notes:

- See attached screenshot for examples with zoom set to 90 % and 95 %
  respectively. With 90 %, the text displays correctly, with 95 %, the
  last line is cut off.

- The used font (at least according to the font selection field of
  LibreOffice is "Liberation Sans" in 10 pt, but changing the font
  to, e.g. "Bitstream Charter" exposes the same behavior (though
  differently at different zoom levels).

- The cell height seems to (more or less?) properly adapt to the zoom level:
    100%: 98 pixels cell height (content only)
     95%: 93 pixels
     50%: 48 pixels

- The phenomenon occurs independently of the following settings:
  Tools | Options | LibreOffice | View ...
  - Screen font antialiasing
  - Use hardware acceleration
  - Use anti-aliasing
  - Use OpenGL for all rendering (on restart)
  - Force OpenGL even if blacklisted (on restarted)
  (the latter two options don't seem to enable GL anyway
  ("GL is currently disabled"))
