Bug ID: 157894
Summary: Undesirable rendering of dashed line in shapes with
corners
Product: LibreOffice
Version: 7.6.0.3 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Impress

Document exhibiting the bug
Consider the attached presentation. It was produced as follows:
1. New presentation
2. Delete default elements
3. Insert a rectangle
4. Set fill to None
5. Set Line Width to 6 pt
6. Set Line style/type to Dashed
7. Play with rectangle dimensions a bit
You'll notice that the corners have jagged artifacts. While one can understand
why these were produced (rendering each edge irrespective of the intersecting
edge) - it is unaesthetic, jarring, and is not how a person would trace a
dashed path.
I suggest that when we have "small parts of dashing", which do not exceed the
intersection with the other edge; and another edge with a dash intersecting the
edge of the intersection - the "small part of a dash" not be rendered at all.
Alternatively, the placement of spaces between dashes can be follow the
circumference, so that dashes of consecutive edges can (more-or-less) never
intersect.
