Description anscgn 2009-09-01 11:09:04 UTC 
I'm using OOo Writer version 3.1 on MacOS X 10.5 (officially released download). Tried to work with a 200 
page document with images (software user manual). Scrolling page-wise up and down with the page 
up/down keys takes about 2-4 seconds per page on a Mac Pro 8-core machine with 12GB RAM.

I doubt this is the intended behavior, especially on a capable machine like that.

As mouse wheel scrolling is also not usable for skimming long documents (see Issue #90907), there is 
currently no viable way to work on longer documents on the Mac. The previous version 2.4 under X11 
performs fine with the same document. Therefore I rated this issue a defect rather than an enhancement.

As to the cause, although I dont know the source code, I would guess there is something wrong with the 
lazy background formatter/renderer, i.e. it seems to always render the entire document rather than the 
requested pages only. Hopefully this is not too hard to fix.

Do you have activated the "Smooth scroll" feature in Tools.Options.Writer.View?
Then it would be the same as issue 98766.
If not, please try to workaround the problem with "Tools.Update.Page formatting"
right after opening the file.
Comment 2 anscgn 2009-09-01 14:10:22 UTC 
Yes, the "Smooth Scroll" feature caused the extreme lag. Sorry for the noise. Please remove this issue, if it 
is already covered by #98766.

Never mind... it is good to see that other people run into same problems. This
way, we can get info about the "popularity" of an issue.
