            Bug ID: 112166
           Summary: crash adding slide fade transition
           Product: LibreOffice
           Version: 5.4.0.3 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org

This can be 100% reproduced under VirtualBox (Lubuntu 16.04 /w latest HWE
kernel, + 3d acceleration /w 128mb graphics ram enabled in virtualbox).  

Same crash on Intel integrated video.

Crashes with Libroffice 5.4.0 and 5.4.1.

Libreoffice 5.3.4 doesn't crash.

To duplicate...make a two slide presentation.  Slide one has the title set to
"one".  Slide two's title is the word "two" in red.  Contents of slides doesn't
matter.  Select slide transition on the right panel.  Click fade icon.  Instant
crash.  100% repeatable.  

Note: if I change my virtualbox settings to remove 3d acceleration it works.  I
believe this is because it changes the Linux graphics driver to the MESA
software rendering.  Even though hardware and opengl is disabled in Libreoffice
clearly something OpenGL related in the transitions is still version specific
and crashing.

Note: If I switch my laptop from integrated (intel integrated i7 2620m) to
nvidia graphics the problem also goes away.  So again...something in the OpenGL
fade transition is crashing.  Maybe you are calling openGL 3+ calls which crash
the older drivers?

There are many bugs related to broken transitions going back multiple years. 
:(  They are all broken in different ways (flashes, white screens/black screen,
screen corruption, crashes) but they are all the same half-fixed bug in my
opinion.
