impress - slide transitions not working

users
#1

Hi all.

I'm having a bit of trouble with some slide transitions.

I've got 3 computers that all behave differently. They all run linux mint, with varying versions of LO installed.

When fed the exact same slide show, with my chosen "dissolve" or "fine dissolve" I find that:

1. on my 64-bit desktop machine (LO 5.1.6.2 mint 18.3) the transition does the dissolve, but with a nasty flicker to a white screen. Other transitions are jerky. nvidia graphics

2. On my 32-bit lappy (LO version not to hand, but still mint 18.3) all works perfectly (intel graphics)

3. On a second 64-bit, freshly installed machine (LO 6.0.7.3/mint 19.2), the "fade" transition is simply a sharp cut. Intel graphics of some sort. Some transitions do work, eg dissolve, push; some fail, eg fade, iris, cube)

I'd originally put #1 down to the driver, but it's as bad with either nvidia's X driver, or nouveau. #3 is bad, as this was to be my backup machine for a presentation next weekend, in case the (elderly) laptop failed.

I'm going to try to downgrade the LO6 to see if that helps, but meanwhile, any thoughts please?

TIA.

(BTW the other working transitions aren't really appropriate for the particular environment. Otherwise they'd be a workround.)

Apologies for following up my own post and for top-posting.

I've been struggling with this and the lack of response. I've now found it's a long-standing problem, back to 2014/2015 and the early 5.x versions. 4.x seems to have been OK. It seems poor that the dev's haven't addressed what is clearly, for some, a long-standing show-stopper regression :-{

I have found that 6.0.x on my 32 bit laptop works fine. I'm wondering if it's a specific 64-bit issue.

Does anyone have a fix that I've missed please?

Hi,

I tried the slide transitions you mention (dissolve - both fine and
standard, and fade - with both offered variants) and I cannot see the
effect you are describing. If it can help, this is my running
environment:

Libre Office Version: 6.3.3.2, installed from the LO Web site - not the
distribution that the OS delivers via its repos.
Build ID: a64200df03143b798afd1ec74a12ab50359878ed
CPU threads: 4; OS: Linux 5.3; UI render: default; VCL: gtk3;
Locale: en-US (C); UI-Language: en-US
Calc: threaded

The OS (uname -a) is:
Linux 5.3.15-200.fc30.x86_64 #1 SMP Thu Dec 5 15:18:00 UTC 2019 x86_64
x86_64 x86_64 GNU/Linux
Desktop is Gnome Version 3.32.2

The computer itself is a:

Hewlett-Packard HP ProDesk 600 G1 DM
CPU: Intel i5-4570T @ 2.90GHz
Memory: 16GB
Graphics: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor
Integrated Graphics Controller [8086:0412] (rev 06)
Viewsonic VA926 19-inch LCD monitor, 4:3 aspect ratio.

Based on that, it is probably not the 64-bit version that is causing
you issues. I did notice that the "Cube" and "Helix" transitions, when
set to last for 2 seconds are not smooth on my machine (but 1 second
is OK). Could it be that your slides contain a lot of information and
that your processor cannot keep up with the load? Do you have something
else running on the computer that is slowing it down? Did you try
changing the transition timings and see what it does?

Sorry I cannot provide more insight.

I hope this helps.

Rémy.

Thanks for the comment.

I'm quite bemused by what I observe.

On the spare Celeron, the appimage works fine. But the same appimage on my desktop box (now upgraded OS) fails with an even worse flicker than before.

I've tried both nouveau drivers and also the integrated video interface: the exact same problem. Yet booting off a live CD and running the exact same appimage with the exact same .odp file works perfectly (I've not tried the 'live'-provided packages).

I've also just found - only on my desktop box - that it won't recognise any audio file to use with a slide transition: this is fine on the spare machine and the laptop. Suggests there's something very amiss with the mint installation on my desktop; time to reinstall, perhaps.

Yet, it can't be all down to one bad installation: slides flicker on the spare with the mint-provided packages, and also on my wife's desktop (also mint 18.x). I'll have to think about this a bit.
