Summary: presenter console: slide transition jumpy
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: UNCONFIRMED
Version: unspecified
Component: Extensions
Product: LibreOffice
Problem description:
I recently upgraded my old Debian laptop from lenny with OO (3.2.1) to wheezy
with LO (3.5.4). I have used the presenter console with OO-Impress in a
two-screen setup before and it worked like a charm.
In LO however the presenter console shows some weird behaviour on animated
slide transitions: While loading the next slide preview the transition pauses
for about half a second - which looks really crappy on animated transitions
(especially because I use it for backdrops on stage - that's one of the reasons
why i use Debian stable btw.).
A workaround is to switch to the slides preview dialog: as soon as the preview
area is not drawn (because it's hidden behind the slide overview) animations
run smoothly again. This however is cumbersome, because in
the overview focus does not follow the current slide, so using the presenter
console becomes somewhat pointless... running the presentation without the
presenter console extension works flawlessly too, but in a stage environment
the preview definitely is nice to have.
Steps to reproduce:
1. install presenter console extension
2. create a presentation of some fullscreen images (i use image files in our
beamer's native resolution of 1024x768 - so these are rather small files)
3. select some animated slide transitions
4. run the presentation
Current behavior:
on every slide change the transition animation starts to run, but after a
fraction of a second is interrupted while the next slide's preview is drawn in
the presenter console.
Expected behavior:
a smooth slide transition
It wouldn't even matter if the transition is delayed until the preview is drawn
(it's only some 1/10s of a second), but it's the "hickup" kind of interruption
that looks ugly.
