Description user234683 2018-10-12 08:58:57 UTC
Description:
When a drawing has a connector between objects, and the middle line of the connector has been moved significantly, and the whole drawing is selected and copy and pasted into a writer document, the middle line will be offset randomly. See attached image.

Steps to Reproduce:
1. Create a connector between two objects in draw. Make sure you form a connector with an adjustable middle line.
2. Move the middle line by a significant amount. Moving it to imitate a connector with only two lines is generally enough. If the bug isn't reproduced, try moving it farther.
3. Select the whole drawing. Copy and paste it into a writer document

Actual Results:
The middle line of the connector in the pasted drawing is offset randomly, neither to where it started originally nor where it was moved to.

Expected Results:
The middle line should remain where it was in drawing.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
Resizing the pasted drawing at all will reset the middle line to its original position when the connector was created (NOT the position it was adjusted to in step 2.)

The bug happens with and without "Use OpenGL for all rendering" enabled. But regardless of whether I have that enabled there's some text below it that says "GL  is currently disabled." Not sure if that refers to OpenGL.

Forgot to mention. I don't believe this is related to https://bugs.documentfoundation.org/show_bug.cgi?id=54355 which is somewhat similar. Zooming has no effect whatsoever on it, and grouping the drawing before copying it doesn't prevent it.

Comment 4 Xisco Faulí 2018-11-13 10:55:32 UTC
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

working example

Here's an example which I've just tested with Libreoffice 6.1.4.1
The reason your sample doesn't exhibit the bug is because it doesn't have the middle line (the connector needs to have a total of 3 lines, and the middle line needs to be adjusted from its default position). So the connector needs to be between two points such that the middle line is present. The position of this adjusted middle line is messed up when copying it into a writer document.

Once the update is finished on my other computer, I'll test it on 6.1.3 as you requested.

Tested on 6.1.3.2 and it still occurs.

Comment 9 Terrence Enger 2019-01-04 04:05:17 UTC
Working on debian-buster with bibisect-linux-64-6.1 repository, I find
that that bug entered LibreOffice somewhere in roughly 1200 commits:

                     commit    s-h       date
                     --------  --------  ----------
    bfr first crash  c5420f11  e1b247a8  2018-04-06
    first crash      c91d6907  6c14c27c  2018-04-06
    last crash       083cb644  bdccb7e9  2018-05-07
    aft last crash   c28a56d0  91b0d212  2018-05-07

Each crash was a Signal 6.  The commits from "first crash" to "last
crash", so far as I probed them, terminated with Signal 6 upon
<Ctrl>+V in Writer.  Some later commits, starting with the one
labelled "aft last crash" displayed the expected result after <Ctrl>+V
in Writer and then terminated with Signal 6 upon <Ctrl>+Q.  I have not
made any attempt to dig into the crashes.

I am leaving keyword bibisectRequest: perhaps the crash is peculiar to
my setup.
