Buggy transitions in Impress Version : 5.1.1.2

I am using LibreOffice 5.1.1.2 on Ubuntu 15.10

The default one (version 5.0) that comes with Ubuntu 15.10 had no problem, But I wanted to upgrade to 5.1, So I did this :

sudo add-apt-repository ppa:libreoffice/ppa -y

sudo apt-get update

sudo apt-get dist-upgrade

to get the latest version,

###But “slide-transitions” in this version is not smooth

The effects like “tails” and “helix” were smooth on 5.0 but its weird on 5.1
