--- Comment #19 from Justin L <jluth at mail.com> ---
Proposed fixes so far:
https://gerrit.libreoffice.org/c/core/+/88910 tdf#80194 UI: revert subscript
DFLT_ESC_SUB to 8% (from 33%)

https://gerrit.libreoffice.org/c/core/+/88911 tdf#80194 editeng: fix auto
subscript calculations

None of my fixes will be related to "fixed line spacing". If you use ridiculous
values for superscript (like 400%) or set it to automatic, I think you will see
that superscript is actually not fine.  It is just that the default value is
appropriate.

Actually, that is the key to the whole fix.  Only 20% of the font height is
available for subscript-shifting while the remaining 80% is available for
superscript. So subscripts need to lower a much less percentage than
superscripts can or should.

Another fix needed is to set the "automatic" flag to superscript/subscript when
it is set using the toolbar .uno:SubScript. However, I want to wait with that
until the next release (7.1) because older versions will calculate auto very
wrongly (see comment 7's note that "Setting the automatic flag in Impress makes
the issue even worse...").
