Impress gets unacceptably slow, produces errors and occasionally hangs when working with multiple jpegs. System: Intel iMac, 2.66 GHz Intel Core 2 Duo, 4GB of RAM OOo 3.1.1 (build 000311m19) on Mac OS X 10.5.8 (latest patches). Step by step: 1. create plank presentation 2. import jpegs one by one. I used the method of dragging them from a folder in Finder to an empty slide. I use jpeg (photos) of about 1 MB each. I put one or 2 pictures on one page. I do not change/edit the pictures other than moving on the slide 3. after about 8 or 10 pictures the display does not get updated and the CPU load goes up and uses approximately one core at 100% - with no other activity. Pictures are not rendered in Slides pane anymore, e.g. When trying to edit *any* object, the spinning beachball often shows up. 4. Adding more pictures (I need about 40 or more for a presentation) leads to errors (cannot move or edit in a controlled manner). Impress is not usable anymore. 5. Removing some slides or images from the presentation reverts the system to normal operation.

The non painting thumbnails in the slide pane are reproducible on windows, too. But the bad system performance seems to be a mac only... Reassigned. Adding hdu as cc.

Profiling the scenario (a presentation with a couple of slides each just containing a big JPEG) shows that reading and decoding the JPEGs costs a lot of time. @sj: Aren't they already in the graphics cache? IIRC there were changes in the way the checksum was calculated and/or cached; could this have had a negative impact on the cache hit ratio?
