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.
