Description A. Fakhouri 2013-04-17 22:17:31 UTC
There is a poor performance when using images; the performance suffers even worse when the images are numerous, large, vectors (svg), and/or when they exist in a large document and/or when they have some transparency (like svg, png, gif, ...etc.). Performance also suffers significantly when scrolling rapidly within a huge file and when exporting to PDF.

A known WORKAROUND for SOME OCCASIONS is to transform the image into a JPG format (to reduce the size and get rid of the transparency -- perhaps using a white background -- ; I also noticed that JPG renders faster in LibreOffice, but I can not confirm that for now!) and to make it smaller. This will make the application hang less, and export to PDF faster! YET, this doesn't solve the problem completely, and the performance still suffers anyway.

I hope we can get a fix for this too.

What Linux distro and desktop environment are you using? What graphics card?
Set to UNCONFIRMED, if the bug is still happening and provide sample files for testing. RESOLVED WORKSFORME, if not.
