When you set the mouse between the cards, the window moves and not the cards. If you maximize the window and you put the mouse between the cards, the window will minimize.

Reproducible: Always

Steps to Reproduce:
As said before: You put the mouse not exactly on the cards and everything moves but not the cards.

Actual Results:  
I had or to recenter the window or to maximize again. But when you play you do not pay very attention where you set the mouse.

Expected Results:  
no more moves of the window
