        <pre>Description:
I made an element transparent, I put it in background, and I moved some element
which were in front of this element. After few seconds, Libre Office draw began
slow and xorg crashed.

In the syslog journal I see:
libreoffice-draw.desktop[16874]: ** (soffice:16892): WARNING **: Unknown event
notification 36
gnome-session[15884]: (tracker-miner-fs:16055): Tracker-CRITICAL **:   (Sparql
buffer) Error in task 0 of the array-update: UNIQUE constraint failed:
nie:DataObject.nie:url (strerror of errno (not necessarily related): Aucun
fichier ou dossier de ce type)

I have Ubuntu Gnome 16.04

Steps to Reproduce:
1. Create an element E1
2. Create an other element E2
3. Change the transparency of the element E2
4. Put the element E2 in background
5. Move the element E1

Actual Results:  
LibreOffice Draw began slow or/and xorg crash

Expected Results:
no crash


Reproducible: Sometimes

User Profile Reset: No
