problemi con archicad 15 - mesh

[Antonio Fabbricatore]

Hello everyone, I need a hand. I have just passed from pc to mac and downloaded archicad 15 for mac, everything works well, I only have a problem that I can't solve: when I make the general perspective the walls are almost transparent and the mesh are blurred. Can someone help me solve this problem? Thank you.

I put some photos to make you better understand the problem
