Description Bryce 2016-04-03 19:18:52 UTC
Presenter Console enabled causes the animation transitions to be choppy. The only time it is enabled is with a second screen. Without the second screen it's smooth and without Presenter Console enabled it's smooth. It doesn't matter if the presenting screen is the main display or the second display it will be choppy if Presenter Console enabled. Disable and animation will work properly on either screen.

Bryce : pleae provide a sample Impress file containing the transitions and step by step explanations of how to reproduce the problem, thank you.

Actually I am not running multiple spaces unless you consider having a second display (in this case a projector). Sometimes I run a second if I am using Prezi, but not with LibreOffice.

Here is a file that can demonstrate what I am showing.

Problem: When using Presenter Console in Impress the animation is very choppy.

How to reproduce the problem
1. go to preferences and choose impress
2. Click General
3. Check the box for Enable Presenter Console

press F5 or start the presentation. The animation is very choppy on the second screen.

To make the problem go away turn off uncheck Enable Presenter Console and start the presentation and the animation will be very smooth.

Your test file is OpenXML, i.e. Powerpoint ?

Do you see the same problem with an Impress (ODP) file ?

OKay so tested with 


on OSX 10.11.6

with a Thunderbolt display attached to a MacBookPro retina


How to reproduce :

1) Load the test file into Impress

2) Keep the Impress window on Macbook screen, do not move it to the separate display.

3) Press fn+F5 on MacbookPro keyboard

4) The slideshow appears on the separate display (Thunderbolt display), and the Presenter Console appears on the Macbook Pro retina screen

5) Now use the arrow keys on the Macbook Pro keyboard to move slides - notice how the transitions become choppy.

Note : I can not reproduce the problem if I drag the Impress window to the separate display first, then launch the slideshow. In those circumstances, the slide transitions remain smooth (at least from my testing), so this could be a workaround. The Presenter Console still gets displayed on the MacbookPro screen irrespectively.
