The outdev code was largely refactored starting Mar/Apr 2014 by Chris S. and
has had a lot of continued work. With current 5.0.2.1 RC1 release I really
don't see much lag on scrolling onto pages with EPS present.

Attachment 58882 for example (a much more complex example of handling EPS
Impress) moves about nicely. And when majority of those EPS are extracted and
pasted into a Writer document--no issues with scrolling in Writer either.

Believe this can be Resolved WFM.  But please reopen if there is a reproducible
test case with current release.

--- Comment #11 from Jean-Sébastien Gosselin jnsebgosse...@gmail.com ---
Using libreoffice-writer 1:4.2.1-0ubuntu1~saucy1 on Ubuntu 13.10 64 bit and I
am experiencing this bug as well.

Would it be possible to have some details about the current status of this bug
please?

I would be so glad to be able to work efficiently in Writer with a document
containing eps. Currently, I either have to disable graphic display or use png.
I think that having a poor rendering of eps in Writer would be 100 times better
then poor vertical scrolling. I can see why some people may disagree with that
though... I'm talking only for my particular situation.

For example, I find the way Scribus is handling eps quite wonderful honestly.
eps are rendered as a low quality preview (quality can be user defined),
allowing you to move things around really smoothly. It is possible to activate
a Preview mode of the document that will improve the rendering of the eps, but
make the document less responsive.

I tracked a regression down to this commit:

commit c0ce7ca4884f7f6d1016bd1dbcc22066cb4a7797
Author: Tomaž Vajngerl qui...@gmail.com
Date:   Sat Jul 7 13:07:03 2012 +0200

Prescale image with Bitmap::Scale to improve quality.

In OutputDevice, when sending the Bitmap to native renderer, use
Bitmap::Scale operation to improve quality when doing sub-sampling.
With this Bitmaps in certain Widgets will look a lot better.

Cleanup and translate comments, and move sal_Bool to bool in outdev2.cxx



This commit improves the quality of the rendering but also adds unnecessary
rerendering of EPS figures when scrolling.

@Sasha: Can you also confirm this scrolling problem with Windows?  I can't
confirm it on my Windows PC, the scrolling works fine as expected.

--- Comment #3 from A stgohi-lob...@yahoo.de ---
the scrolling problem is for me not reproducible with LO 4.0.2.2 (Win7 Home,
64bit)

But I can confirm as per Sasha's comment that on page two there is only an
empty square.

Does this issue still persist for you with the latest release of LO?

If not, then I would propose to close this issue, but to open a new bug report
regarding the red square on page two.

[This is an automated message.]
This bug was filed before the changes to Bugzilla on 2011-10-16. Thus it
started right out as NEW without ever being explicitly confirmed. The bug is
changed to state NEEDINFO for this reason. To move this bug from NEEDINFO back
to NEW please check if the bug still persists with the 3.5.0 beta1 or beta2
prereleases.
Details on how to test the 3.5.0 beta1 can be found at:
