Dragonball z Legends stuck at events

When I want to switch out charachters or a meteo appears, (beams/specials)

Sometimes he just pauses and hangs after a certain time at a always a certain point... Sometimes after the special the screen goes white before it goes to gameplay as normal but sometimes it hangs white...

Here some vids...:
