LibreOffice doesn't have an icon

LibreOffice ist great. It's free software, people sat down in their free time and did/still do all the work.

But it is barely usable if your presentation relies on any video. Impress (the presentation software) does not manage to play videos without 1) hogging the CPU, thus being unresponsive during playback (e.g. can't change slides) and 2) producing random artifacts in the video during playback. Happens on both Arch Linux (my laptop) and Ubuntu (colleague).

If I understood correctly it uses gstreamer Linux. Running the same videos in Totem (video player using gstreamer), everything works. So the problem is with Impress.

This led me to grab a spare MacBook Pro from the office to give a presentation recently (thank god there is one). I'd love to see this issue fixed at some point.

What does a generic LibreOffice application do anyway?
