Description Eick 2019-09-04 22:23:09 UTC
Description:
Libre Office (6.3.0.4) Draw
System: Windows 10

Step 1 -> launch Draw and draw a couple of circles, ellipses and other rounded shapes, and a square, making sure to space them all well fro one another.

Step 2 -> apply colored fills to all of any types (eg. single color, 2-color radial or linear, etc.)

Step 3 -> put two rounded objects diagonally close without touching or overlap them in any way (one partly on top of other). In one of them set the fill to transparent, and make it overlap the other (drawing order on top)

Step 4 -> export to PDF, open PDF see the false black fills on the rounded objects that have no transparency.

Steps to Reproduce:
1. launch Draw and draw a couple of circles, ellipses and other rounded shapes, making sure to space them all well from one another.

2. apply colored fills to all of any types (eg. single color, 2-color radial or linear, etc.)
 
3. put two rounded objects diagonally close without touching or overlap (touching) them in any way (one partly on top of other). In one of them set the fill to transparent, and make it overlap the other (drawing order on top)

4. export to PDF, open PDF see the false black fills on the rounded objects that have no transparency.

Actual Results:
non-transparent objects drawn close (in case of circles and ellipses) or behind a transparent filled object have their fill changed to black.

Expected Results:
Expected to keep the correct fill colors on such situations.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Software should work better with transparent objects close or overlapping non-transparent ones especially in case of circles and ellipses.
