LibreOffice Writer 4.2.1.1 lagging

I have a user who has a ODT document with graph pictures in the document. The document is only 48KB. But user experience serious lagging when open the document.

Opening other ODT documents does not have this problem. However, when copy the graph pictures to a new document. The new document also experience the same problem. The graph picture was copied and pasted from a third party software. Before upgrade to 4.2.1.1, user doesn’t have this problem with graph pictures.

I have increase memory and disable hardware acceleration in the Options, but problem still exists. Please help.
