Description Xisco Faulí 2018-05-02 10:12:02 UTC
Created attachment 141831 [details]
How it looks in LibreOffice 6.1 master

Steps to reproduce:
1. Open 140574 from bug 116345
2. Select the video
3. Play it

Observed behaviour: Everything around the video become grey. Scrolling the window has an unexpected behaviour as well. The problem remains if we go to the start center or to another component.

This is not reproducible if we zoom out the slide before playing the video...
Not reproducible in GTK nor GEN

Caolán, I thought you might be interested in this one...
Comment 2 Caolán McNamara 2018-05-02 11:32:42 UTC
Might be using the fallback if the gstreamer gtk integration is not installed, for me I have...

/usr/lib64/gstreamer-1.0/libgstgtk.so (from fedora 27 gstreamer1-plugins-bad-free-gtk-1.12.4-1.fc27.x86_64) installed and I don't get the all-grey look you get. 

What's your distro and is that libgstgtk.so there, and if not, is it available via some package or other ? If it was that problem its possibly to add specific requires to our upstream rpms to make it a requirement
Comment 3 Xisco Faulí 2018-05-02 12:16:40 UTC
Hi Caolán,
I have Linux mint 16.04 with gstreamer 0.10.36-1.5ubuntu1 and 1.8.3-1~ubuntu0.1 ( with gstreamer1.0-plugins-bad ) but I can't find libgstgtk.so
Comment 4 Caolán McNamara 2018-05-02 12:41:39 UTC
Maybe /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstgtksink.so ?

Yes, that lib exists in the same folder you're mentioning...
Comment 6 Caolán McNamara 2018-05-02 14:37:23 UTC
Got the best available renderer in place then, so possibly I'm insulated from this by using wayland or there's something else gone wrong, like event starvation or some such

No longer reproducible since the video is played in another window in
