Description Carla sella 2011-10-23 06:28:17 UTC
Created attachment 52650 [details]
A draw document used to draw network configuration

Problem description: 

Steps to reproduce:
1. open attached document (MyNet.odg)
2. try to scroll it up and down

Current behavior:
It's very slow and screen on Ubuntu 11.10 (it also happened on Ubuntu 11.04) goes gray for a while, it turns normal but scolling is sluggigh

Expected behavior:
Normal scrolling of document up and down and sideways

Platform (if different from the browser): 
Ubuntu 11.04 and Ubuntu 11.10 64 bit
Browser: Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1

This used to happen also with Libre Office 3.3.2.

This same Libre Office Draw document opened under Windows 7 has absolutely no problem related to CPU usage and I can scroll it and work with it normally.

I have already reported a bug on launchpad:

Sorry in he "current behaviour" section "sluggigh" stands for sluggish (it was a typing error)
Comment 2 Carla sella 2012-03-08 12:43:39 UTC
I am currently using Precise Pangolin Beta 1 with all updates installed and the problem is even worse, it's impossible to modify the document.
I really need to work on odg documents but it impossible with this bug, are you going to do something to fix it ? it's been quite a long time since the reporting of this bug.

I'm not a developer but I confirm that the scrolling behaviour is subotimal in as well (Build ID: 350ae8294a8df78403fd8cdce56b9aeb8178e13) using Vista 64bit.

however I would not call it sluggish... In my test it was choppy (in italian "scattoso")

I guess it is a bit sluggish or choppish.

scrolling is shill "choppy" using LibO and alpha

the bug is easier to reproduce if you scroll using arrowkeys
Comment 9 Carla sella 2017-01-15 15:20:57 UTC
I have tested the attached file on Window 10 with Libre Office and the issue is solved, the file can be scrolled just fine.
On Ubuntu I have Libre Office (this is the version Ubuntu installes) and also there the issue is gone, everything is ok.
