Description phv 2022-06-19 16:12:42 UTC

Description:
This is a bug that exasperates me because the rendering on pdf is affected; When a border is added to a frame, the top and left lines are shifted by one pixel leaving the background of the frame on both edges.

Steps to Reproduce:
1. Create a new Writer document.
2. Insert a frame.
3. Fill the frame area with a color.
4. Add all four borders with another color.

Actual Results:
Top and left border lines have a one-pixel gap with the frame edges.

Expected Results:
Top and left border lines shouldn't show any gap with the frame edges.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
This is not a software rendering issue since the gap is also seen after exporting the document to pdf format. Furthermore, the tables are not affected. This is a result of a wrong calculation in the placement of the border relative to the frame.

This behavior is all the more damaging since frames are often used as decorative elements.
