Wearisome performance of Impress in Mac OS X

Hope someone can help with this:

I’ve got the latest Impress running on my MacBook Pro with Mac OS X 10.6.8.

For the past few months I tried really really hard to make all my presentations with Impress. The big problem is that it’s performance is the exact opposite of snappy.

After adding images (they are just 500-800kb JPGs) to, say, 20 slides, Impress comes almost to a halt. Things respond 1-2 seconds after the mouse click.

This is especially frustrating when clicking, holding, the dragging, because there is always a 1-2 second lag between each step. For instance, if I click and drag the corner of an image to resize it, the motion is not smooths, but rather occurs in “jumps”. Another instance would be when I click on a slide to select/show it in the main window. If I move the mouse cursor away after clicking on a slide, the lag makes Impress think I am dragging and re-ordering the slide! And of course there is a few seconds delay here as well.

So my question is: What’s wrong that’s making Impress perform so poorly?? My Mac has a Intel Core i7 2.66 gHz CPU, advanced Nvidia graphics, and 8.0 GB of memory, it should be overkill for something like this! I tried tweaking the number of objects kept in memory, size of objects, etc. to no avail.

Is it just because Impress has poor performance? (in which case I think it really need to be improved) Or am I doing something wrong??? M$ PowerPoint and Apple Keynote works beautifully and snappily, but I wish I could use Impress!

Maybe this extension can help to improve:

Libreoffice comes with a good presenter screen function. But that is not related to the poor performance I am getting. Any other ideas? Thanks!

Hi @penyuan,

It’s possible that there’s something weird going on in your particular document or on your particular machine. If it’s the former, we can help you triage it!

Please file a bug about this problem and include a sample document that exhibits this behavior. If you have personal information in your presentation, please replace the images with with other images of the same general size, etc. The most important thing is that the document you submit is shows same slowdown that you’re experiencing with your regular documents.

The QA team will be happy to help you track down this issue!

If you do file a bug, please post a link to it in a comment below using the format “fdo#123456”.
