Description dg1727 2014-02-02 00:48:55 UTC
1.  Create a new document in LO Writer.  
2.  Type a sentence.  (I wrote one that was a little more than one line long.)  Press ENTER at the end to make the sentence into a paragraph.  I did this twice to leave a blank line between paragraphs.  
3.  Use copy-and-paste to duplicate the paragraph a couple of times.  
4.  Using the mouse, select (highlight) a word.  
5.  Try to drag-and-drop the selected text to somewhere else in the same document.  Keep the left mouse button held down while you move the mouse around to various candidate drop locations.  There is normally a vertical checkered bar, like a text cursor but checkered, that previews where the dragged text would be dropped if you were to release the mouse button.  

Issue:  This checkered vertical bar has too much lag in following the mouse.  Sometimes it doesn't move at all to a given position between 2 characters until the user has tried a dozen times or more.  

This appears to be a regression.  I don't remember the last version of LO I used that didn't have this issue, though.  

LibreOffice on Ubuntu 13.04.  I'm using the "libreoffice/ppa" PPA from launchpad.net.

Dear dg1727,

I can confirm this is there in 4.1.6, 4.2.5 and 4.3.0 on Linux Mint. It is a regression as it doesnt happen in 4.0.6, and the delay time for the cursor to move to its new location maybe just half a second.
Comment 2 Yousuf Philips (jay) (retired) 2014-07-07 15:17:21 UTC
This behaviour only seems to happen when following the steps provided, as the regular drag and drop in other files dont show this issue.
Comment 3 Joel Madero 2014-07-16 04:47:53 UTC
Minor - can slow down professional quality work but won't prevent it
Medium - default is low, bumped up because of regression

Comment 4 Matthew Francis 2015-01-20 03:04:10 UTC
I got a different bibisect result from this - to be taken with a pinch of salt, the bug may not be as reproducible as it seems

Comment 5 Matthew Francis 2015-01-20 03:16:05 UTC
Probably the below commit (again) - there was a recent commit on master relating to this under bug 73165, and indeed when I check, this bug seems resolved on master now
