Subject: tdf#125949 Allow the slide to continue with freezing animation.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Entrance (Zoom in, Spiral in, Sviwel, Stretchy) animations with
shapes freezes the presentation when OpenGL is enabled. As a
workaround, avoid playing these animations.
