Bug ID: 120525
Summary: percent linespacing <100% bug with fonts with big
descent
Product: LibreOffice
Version: 5.4.5.1 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Impress
Assignee: [email protected]

font with big descent
If font have "big" descent values, setting linespacing percent has no effect
until a certain value.
to reproduce :
- use the attached font (descent=646 ascent=963)
- write some text, and try to set linespacing to 90% => no change
- changes can be seen for percents < 80%
This doesn't happen with version <5.4.
git Bisecting show that the regression start with this commit :
https://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-6-0&id=81827ab543d27af82dd7b432f860bf1c473508dc
I don't understand all the mechanisms behind the code, but the culprit is
clearly in this line : if ( !nAscent || nAscent > nNewAscent )
As I'm not familiar at all with libreoffice code, I have done a "minimal"
patch, just to avoid the regression and so the bug #114628 stay fixed by just
applying the new code path for the first line and revert back to the old code
path for the others.
