Bug ID: 118346
Summary: Slow performance in Draw with (moderately) complex
drawings
Product: LibreOffice
Version: 5.1.6.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Draw
Assignee: libreoffice-bugs at lists.freedesktop.org
Reporter: gessel at blackrosetech.com
Description:
When working with large drawings, performance is painfully (though not quite
unbearably) slow - but, weirdly, it seems to get better after working with a
document for an hour or two. Initially, selecting an object might take 3-5
seconds to highlight, selecting a menu might take 10-15 seconds to open, a
pop-over submenu the same. I ran Oprofile, the results are below.
There are some other bugs that are similar, but they have specific conditions
which are not an exact match so this issue may be different.
This is likely related to Bug 100253 (my report) and possibly Bug 54722, but
that was about opening and I have broken up my drawings since to have
individual pages and have never tried to create another complex unified
drawing, so I can't be sure.
Like Bug 65046, I note only one CPU is wedged at 100% (8 thread units are
available).
I strongly suspect this is the same core issue in Bug 76740, Bug 96176, &
possibly Bug 104716.

Steps to Reproduce:
1. Create a large document (mine are a mix of SVG imported templates, connector
lines, and a few raster graphics) - I set the page to "A0" size, which may
create some issues with memory allocation
2. Interact with the UI or attempt to edit the document
3. wait....
Actual Results:
Long waits
Expected Results:
snappy response
Reproducible: Always
User Profile Reset: No
Additional Info:
OpenGL generally crashes LO and I have to edit the config file manually or do a
complete deinstall and reinstall, thus losing all my UI customizations. I
strongly, strongly suggest never ever enabling OpenGL without testing on a
machine with snapshots so you can roll back - or at least backing up
preferences first. But that's a whole 'nother issue. Short: no haven't ever
successfully tried OpenGL.
