On pc Debian x86-64 with master sources updated some days ago, I could reproduce this (gen rendering).
I got this bt:
#0  0x0000000000000031 in ?? ()
#1  0x00007fffef7e74e0 in sdr::event::TimerEventHandler::Invoke (this=0x55555bc8dd10) at /home/julien/lo/libreoffice/svx/source/sdr/event/eventhandler.cxx:113
#2  0x00007fffec8ae81b in ImplSchedulerData::Invoke (this=0x55555ba75320) at /home/julien/lo/libreoffice/vcl/source/app/scheduler.cxx:46
#3  0x00007fffec8aec7b in Scheduler::ProcessTaskScheduling (bIdle=true) at /home/julien/lo/libreoffice/vcl/source/app/scheduler.cxx:159

The weird thing is I got a crash just opening and selecting the image (so without changing slide) with gtk3 rendering.

Comment 4 Julien Nabet 2017-06-21 08:35:05 UTC
Caolán: thought you might be interested in this one since there's an extra pb with gtk3 rendering.

(let's increase importance since it's a crash+regression)
