I need 1 minute. Windows swaps a lot in this time. You cannot work with 
such a presentation, because each situation, which needs a redraw of the 
view, takes this time.

If you break the file, you get more than 10000 draw objects for the 
upper picture. The time for breaking up is much shorter. So it is not 
only the huge number of objects, but something in the way the metafile 
filter works.

I have exported the file to odp-format in PowerPoint. The odp-file shows 
the same slow handling of the metafile pictures. So the problem is not 
in the ppt import filter.

The file is a good example, so please open a bug report.

Kind regards
