Bug Description

I created an Impress presentation with about 50 slides, many pictures, file size about 13Mb. When I perform the slideshow, after a few minutes, one of the 2 cpus of my Centrino duo (on a Dell Latitude D620 laptop) goes 100% use (as reported by system monitor) and averything performed inside Impress, including going to next slide becomes increasingly slow.

Using Ubuntu i386 desktop 7.10 with the latest updates.

Thanks

I confirm the problem appears also with another presentation, thus it does not seem to be specific for the file I attached. It looks like if the problem is elicited by browsing the slides backward and then forward again during full screen presentation (F5).

Additional information: massive slowing happens also if I close Impress and then open the file again (takes minutes to load).

Lucio, do your presentations use effects ?

As you can see from the presentation attached above, no effects have been used, but the bug persists anyway!

I had this same problem. It is very annoying, and causes long delays during a presentation with Impress. Very embarassing! Also save times are increased to ~10 minutes. I can supply the file used to reproduce the bug if it's needed.

I experienced the same bug, after a few minutes of presentation (with or without effects), cpu usage of soffice.bin increases more and more up to 50% (one cpu core)

uninstalling openoffice-gtk and openoffice-gnome fixed it for me

(Ubuntu 7.10 i386, Intel Core 2 Duo, openoffice.org 2.3.0-1ubuntu5)

I can submit the presentation file if needed.

Hi,

i can agree to this. I have the same problem. After a few minutes of working with effects, soffice.bin uses 100% of my CPU.

Perhabs it's because of my ATI Radeon Mobility 7500? Compiz works very fine, but Impress effects are slowly and not smooth. I don't understand it.

My system: Ubuntu 7.10 i386, Intel P4 2,4 GHz, 512 MB RAM, OOo 2.3 - ATI Radeon Mobility 7500

Maybe this can help:
I noticed sometimes the 100% CPU use persists even when Openoffice has been closed. Anyway, the CPU cools down to 0 if I close "Mail Notification 4.1" icon removing it from notification area.

It doesn't work for me, because I haven't installed the Mail Notification-Tool. Are you shure that this is really working?

Maybe it's a good idea to merge this Bug with -> https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/160173 ?

Comfirmed PaulK's work around is working. I can get the job done with non native gui for OOo.
