Bug ID: 119794
Summary: Formula objects cut off vector arrows
Product: LibreOffice
Version: 5.1.6.2 release
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: dmhym...@hotmail.com
Description:
The vector arrow placed over elements in the formula editor renders outside the
border of the formula when shown in Writer. This issue occurs for arrows
produced by both 'vec' and 'widevec', but does not apply to other modifiers
drawn above characters, such as 'bar' and 'hat'. Including 'bar' or 'hat' in
the same line, or extending the height of the formula by other means, reveals
that the vector arrows are drawn, but are cut off by the bounds of the
rendering window.
Vector arrows are visible while the equation editor is open, but are not
rendered properly once the editor is closed and editing the document resumes.
They are also not printed properly, or exported properly to PDF.
A similar bug appears if a vector arrow is placed above an element in the
denominator of a fraction expression; the arrow overlaps the horizontal
dividing line. In this case, the arrow is also not visible while the equation
editor is open.
It seems that the vector arrow may not be marked as having height, so it does
not move the formula border or other elements, such that it can be drawn
unobscured.
Steps to Reproduce:
1. Open formula editor in a new blank document
2. Enter the formula "vec E = - vec nabla V"
3. Close the formula editor
Actual Results:
Vector arrows above E and nabla are not visible. It is evident that some accent
is present above E, but the nature of the accent is not apparent.
Expected Results:
Vector arrows above E and nabla are rendered within the object.
Reproducible: Always
User Profile Reset: Yes
