--- Comment #13 from Nikolay Sivov bunglehead@gmail.com --- It works just fine for me, Office14 PowerPoint Viewer with a document you linked to - animations work smoothly, slide transition works too. I'm running latest wine from git. It's possible that your packaged wine dependecies are messed up or something like that.
And you need to set riched20 as 'native' for this prefix. Let's wait for someone else to confirm but this is fixed or invalid imho.
