Arturia plugins (V5) make Cubase stop playback see video!

I have experienced this bug with many (if not all) Arturia plugin from V5:

After initializing a plugin - after some time the GUI will disappear for a short while and this causes playback in Cubase to stop!

Only happens at first playback.

Maybe copy protection related?

Only happens with Arturia synths.

VERY annoying . please look into this Arturia / Steinberg.
