sample of odg file with EMF files

Hello I'm using LibreOffice Draw 4.2.2.1 to work on some documents with some EMF images.

It is since some versions of LO (not sure how many, but I think should be since 4.x) that when I insert the image "from file" the document is almost stuck: it is very slow on moving and resizing the image (almost a couple of seconds every movement).

The problem is mainly on EMF files. Using OpenOffice this problem is not present.

I'm working on these files since many years ago, and in the past I never had a problem with this EMFs.

To continue work I must switch to OpenOffice, but I would prefer to keep LO.

Thank you

reproducible with the attached sample file using LO 4.2.2.1 (Win 8.1)
Comment 2 Alexandr 2014-03-29 09:57:51 UTC
Reproducible with LibreOffice Draw 3.5.4, 4.1.4.2 and 4.3.0.0.alpha0+ Build ID: 926435ef5ab26e647c09887d471bde25b24e1c16 TinderBox: Linux-rpm_deb-x86_64@46-TDF, Branch:master, Time: 2014-03-22_00:09:10 on Debian x86_64

The problem is not only with moving/resizing the schemes. Whole interface becomes slow when the problem pictures are displayed. I was able to freeze my system by simple moving Help->About window.

The issue is sensible to anti-aliasing. Disabling it makes Draw usable (Tools->Options->LibreOffice->View->Use Anti-Aliasing).

Already tried to uncheck antialiasing, but nothing has changed
