To “solve” it, I have changed all my Primary Card to Secondary Card.
That’s a very interesting bug – have you modified the Primary card styles? I’m thinking it may have to do with shadow or opacity or a similar setting, but not sure 
It’s seems something is broken with the Primary Card and also with the Open Page Flow. A lot of users have the same problems.
