No crash for me with LO 5.4.1 from Ubuntu PPA and LO 5.4.2.0.0+ built at home under Ubuntu 16.04 x86-64. Both use GTK3 backend.

Please could you give the complete version informations: menu Help > About LibreOffice, right click then choose Select All, then copy, then paste here.

For me I get: 
Version: 5.4.1.2
Build ID: 1:5.4.1~rc2-0ubuntu0.16.04.1~lo0
CPU threads: 4; OS: Linux 4.4; UI render: default; VCL: gtk3; 
Locale: fr-FR (fr_FR.UTF-8); Calc: single

I guess these infos are in the crash report, but it is useful to have them here too.
Set status to NEEDINFO, please set it back to UNCONFIRMED once requested
informations are provided.

Best regards. JBF

Thank you for the reply.

I installed the .deb files from the Libreoffice website.

Version: 5.4.1.2
Build ID: ea7cb86e6eeb2bf3a5af73a8f7777ac570321527
CPU threads: 1; OS: Linux 4.10; UI render: default; VCL: gtk2; 
Locale: en-US (en_US); Calc: group

Does it crash if you use the gtk3 backend ? To try that in a terminal:
$export SAL_USE_VCLPLUGIN="gtk3"
$libreoffice

Set status to NEEDINFO, please set it back to UNCONFIRMED once requested
informations are provided.

Best regards. JBF

Jean-Baptiste Faure,

Thank you for your feedback.

As requested, I ran: export SAL_USE_VCLPLUGIN="gtk"

I started libreoffice with: libreoffice5.4

Still crashes as soon as I click the fade slide transition.

Crash report for this run:

crashreport.libreoffice.org/stats/crash_details/9ba57fd6-aea0-4c55-b756-12b400be158b

Reproduced crash with LO dbg master with GL disabled in VM Ubuntu 16.04 with 3D acc. Intel video inside plus ATI.
Crash report: http://crashreport.libreoffice.org/stats/crash_details/1dad089c-2108-4818-879f-cfffb8d21fe3
Singe slide is enough and any title, no need to change color: http://crashreport.libreoffice.org/stats/crash_details/73428354-20ca-4c9f-a848-a4dbc08bf89b
But signature is different, my is libvclplug_genlo.so.
Anyway, I'll confirm this. First time I tested in Windows, not responding LO. After that, it worked. I wont' change All->Linux for a moment.

Interesting 5.3.4 doesn't crash for jebsolutions. 
5.3.0 crashes for me and 4.2 and 4.4 don't. I'll mark regression and say it blocks Bug 103704. Not sure for Bug 93529.

Most slide transitions use OpenGL, the OpenGL that can be disabled in the options dialog is rendering of the UI with OpenGL.

@Meeks, @Tomaz: Any thoughts on this, as i could have swarn there was some bug that when a VM was set with a specific amount of memory or something like that, that it caused transition crashes.

I updated to 5.4.2 and the crash still exists:

crashreport.libreoffice.org/stats/crash_details/f5b5ff86-62b6-449b-b8cb-9d862920f90f

Tested on Windows 10 Professional.  Libreoffice 5.4.2 doesn't crash with Intel integrated video (i7-2620m).  But the single-frame flicker of showing the previous slide for a split second is still there.

Also, on Windows 10 the top menu (File, Edit, View, insert, Format, Slide...) seems to sometimes flicker or become invisible when I move the mouse over it.  It's like it's being redrawn unnecessarily.

crashreport.libreoffice.org/stats/crash_details/cb1ab943-d136-4f1b-b8ec-1a69061f6554

LibreOffice 6.0.0 RC3 DEB.
Still reproducible under Lubuntu / VirtualBox:

Steps to duplicate crash:
Start LibreOffice
Uncheck the "show this again" to the wizard
Click cancel to give me a blank empty document
on the right click on slide transition
Click fade
instant crash

No crashes from 6.0 -> https://crashreport.libreoffice.org/stats/signature/non-virtual%20thunk%20to%20X11OpenGLSalGraphicsImpl::RenderPixmapToScreen(X11Pixmap*,%20X11Pixmap*,%20int,%20int)

is it reproduce with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/

I think
https://gerrit.libreoffice.org/#/c/59300/
and
https://gerrit.libreoffice.org/#/c/59298/
will make this not crash

Hi, I have attached a document that crashes under LO 7.0. I am running Debian, with a built in Intel video card, using a backports kernel. I do not have glXCreateContextAttribsARB in my GLXinfo.
