Description pablo 2014-09-28 03:05:03 UTC
Hello, I have repeatedly experienced problems with Libre Office Impress in that the screen freezes and the CPU usage gets close to 100% when I use or show a relatively small file of 3.5M (attached). I have searched the web for solutions but have not had any useful hints. I am using an ACer AMD C-70 APU with Radeon(tm) HD Graphics × 2,with 3.6 G of RAM, and Ubuntu 14.04. I would appreciate your help. Thanks

We need more information.

1. Your operating system
2. A test file with reproducible steps
3. Version of LibreOffice
4. Is this a new problem? Regression? Happened for a long time?

Does this happen every time?

Marking as NEEDINFO - once you provide more information please set to UNCONFIRMED. I suspect it might be something with the video card but I could be wrong.

Hello,
I am using Linux Ubuntu 14.04 LTS, and LibreOffice version 4.3.1.2. I
attached in my mail the file there the problem is systematically generated
every time after reach slide # 30. I have monitored the use of RAM memory
and CPU time as the presentation (it is a class) unfolds. I have found that
the % of used RAM memory stays constant (roughly 30-40%), but that the % of
CPU used reaches 100% with one of the processors and 70-80% with the other,
and that they alternate such that one of them is always at 100% of use.
Before writing to the blog, I had tried to change the amount of RAM memory
allocated to LibreOffice, the number of objects and a few other options in
the Tools-->Options-->Memory menu, and have disable the "use antialiasing"
in the  Tools-->Options-->View menu. After these changes there were very
slight improvements but the Impress presentation gets always frozen or very
slow when I reach slide # 30, which is when the % CPU used gets close to
100%.
Any help would be appreciated.

Regards

Pablo
