So if you render thumbnails ahead of time the office becomes unresponsive. I think that that is even more annoying, than the pauses when you scroll through the slide sorter bar. Rendering previews in a separate thread would be a solution to this problem, but VCL does not allow that (well, you could use a thread, but had to lock the global solar mutex when calling into VCL and would therefore still not have concurrent rendering.) Additionally the previews are stored in a cache, that in the moment has a size of 4 GB. With a document of 200 MB size, that probably has a fairly large number of slides, you soon reach that limit. The effect is that unused (i.e. not visible) previews are reduced in resolution or removed from the cache altogether. In that case pre-rendering previews would only waste time. There still is code in the slide sorter for rendering previews ahead of time: calling GenericPageCache::InvalidateCache() at apporpriate times might do the trick. The drawbacks, however, always outbalanced the advantages. Therefore it is currently not used. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
