Slide transitions flashing screen

LibreOffice Impress
Whenever I add slide transitions such as cube, vortex ect. (3d transitions) and the presentation is played (f5), I see only flashing screen with black and white lines.
Other transitions do work properly such as fade.

Extras? In menu?

Sorry, it’s not like that in Ubuntu.

It’s not Extras in Windows either. It is Tools.

Yes, right!
