Description Ricardo Antunes 2023-02-02 13:34:14 UTC

Description:
The Bug appears when adjusting connector lines that are connect between two objects and that have more than 1 edge or angles. 

Can be replicated by moving the middle line handles on the Connector Lines, represented by small red squares.

The effect is that the line does not follow the movement of the cursor, instead it freezes in a "Ghost" shape (usually very different from the original form) and the movement of the handle is not displayed on the monitor and continues on until the mouse botton is released.

I'm currently using LO 7.5, and 7.4 on windows and 7.1.8 on MacOS and this happens since LibreOffice 7 on all platforms (LINUX included). Also tried this with a fresh install of LO and the problem persists.

This is not problematic on simple diagrams but can be a real problem in more complicated and dense drawing schemes.

I would kindly appreciate you help with this issue.
Ricardo A. 

Steps to Reproduce:
By moving/dragging the middle line handles on the Connector Lines, represented by small red squares. Usually with Connector Lines with 2 or Middle Line Handles

Actual Results:
line does not follow the movement of the cursor, instead it freezes in a "Ghost" shape (usually very different from the original form) 


Expected Results:
The application should show the Connector Line moving following the movement of the mouse cursor


Reproducible: Always


User Profile Reset: Yes

Additional Info:
No other relevant info to add.

The error cannot be replicated by moving the objects, only by moving the handles on the Connector Lines. 
The attached .png image is a screenshot taken when I was moving the middle handle and, has you can see, a ghost Connector Line with a very different shape appears on the screen. Also the "real" Connector Line freezes and does not follow the cursor movement during these adjustments.

Hi,

I see the status has been changed to "unconfirmed". I work on a company  with aprox. 20 PCs with installed LibreOffice every PC with LO (<7.xx) installed that I know of has this issue. I also have many friends and family using LO with that have the same issue so I don't understand how can you not replicate or confirm a bug that is present on such a wide sample and variety of machines and versions.

Thank you and keep up the good work

Hello,

Thank you for your replay. I confirm that all versions of LO 6 don't have this issue, this problem started since LO 7.0 onwards.

Same bibisected commit as bug 122735 - maybe a duplicate, maybe not, leaving for now.

This is a regression from the oldest commit in the list, as it's been backported to 6.1, and bibisecting there uniquely identifies the backport:
