Created attachment 101567 [details]
test pdf file

Steps to reproduce:
1. Open the attached test pdf with Draw;
2. Zoom the slide to 100%, and try to scroll up and down with the scroll bar.

Current Behaviour:
LibreOffice "freezes" for a while before the slide is srolled (not smooth).

OS: Windows XP SP3, 3.0GHz CPU, 2G RAM.
Version: 4.3.0.1

Reproduced with 4.2.4.2, 4.2.5.2 and 4.3.0.1 on openSUSE.
The issue is not present on 4.1.6.2.

Draw is not responsive at all while scrolling (the hardware is not the issue, I'm on quadcore i3770 + ssd + amd 7870hd).

Changing Status to NEW.

I partially reproduce the bug with LibreOffice 4.2.5 from Debian Wheezy backports x86_64: scrolling is extremely slow, but Draw does not freeze. Scrolling is perfect in LibreOffice 4.3.0.2 on Debian Jessie. I remember that the issue was awful and scrolling after zoom was impossible for most of (all?) pdf with earlier 4.3 versions. 

Please, try LibreOffice 4.3.0.2 or later.
Comment 4 Kevin Suo 2014-11-26 08:27:05 UTC 
Works for me in Win 7 X64, scrolling is perfect.
I don't use Win XP anymore. Thus mark as WORKSFORME.

@Alexandr: Thanks for testing.
