Description Mike Hitchcock 2012-11-14 15:29:16 EST
Description of problem: Libre Office Impress runs very slow when you have many slides and multiple object per slide.

Version-Release number of selected component (if applicable):

How reproducible: Very easily reproduced. 

Steps to Reproduce:
1. Create LibreOffice Impress presentation 
2. Add 20 slides
3. Add tables with at least 13 rows and 5 columns. Move the object around and create new rows 
Actual results: When moving objects, it sometimes took over 15 seconds for the object to finally move

Expected results: The results were consistently slow as expected.

Additional info: Tried clearing ~/.libreoffice with no success.
Tried turning off Hardware Acceleration
Tried increasing Graphics Cache to 100MB in LibreOffice

We missed this one, sorry...

Yes, larger tables in impress are a pain. Let's see if I can speed it up a bit.
