Impress (5.1) some of the custom animations not working

Various custom animations do not work. Slide transitions ok apart from 1 already reported as bug

OpenGL issue? What are your OpenGL settings?

Tried enabled and disabled settings.
Tested in latest 5.1.1 rc1

I have filed a bug report.

I have the same issue. I looked in Tools > Options under View; OpenGL was not enabled. I enabled it and restarted LibreOffice. The same issue persists.

Tested in 5.2 alpha1.
All animations work.

Can you please point to your bug report?

resolved in 5.2

For me, LO 5.2.2 (Win64bit) crashes on any animation!
