            Bug ID: 131610
           Summary: Impress crashes upon running the second OpenGL
                    transition
           Product: LibreOffice
           Version: 6.4.2.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
If I set up a presentation and use OpenGL transistions with the previews on,
the first transition runs fine in the preview, but if I select a second OpenGL
transition (doesn't matter if it's on the same slide or not), LibreOffice
crashes. I've tried turning previews off, and while that allows me to add all
the transitions I want to a presentation, the same problem happens when running
the actual fullscreen presentation: The first OpenGL transition runs just fine,
the second one crashes LibreOffice. This has been the case for every version of
LibreOffice on every Linux computer I've run it on going back for years. Still
present in the most recent version. This makes OpenGL transistions useless.
I've heard that using the Flatpak version helps, but for me the Flatpak version
shows the exact same behavior. This is on Linux Mint 19.3 (going back for many
versions - can't remember the first version I tried it on), currently on AMD A8
APU (also the same on various other AMD APU's, CPU's, and GPU's I've used).
Running the open source graphics driver. OpenGL info: OpenGL version string:
4.5 (Compatibility Profile) Mesa 19.2.8 (from glxinfo). I have tried resetting
my user profile to make sure it wasn't a problem there. The same behavior
occurs on a brand new user profile.

Steps to Reproduce:
1. Open Impress and create a presentation.
2. Add a transistion.
3. Add a second transition.
4. (If previews turned off) Run presentation through to the second OpenGL
transition.
5. Watch it crash.

Actual Results:
LibreOffice crashes completely.

Expected Results:
Transitions should all run properly without crashes.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
