Heroes displaying bug

Hi! I have a bug, with witch I can not play. The point is that heroes fall under map or rise above. I have a screencast of the bug, but I can not attach links here.
Is there something I could do to fix that?

Hello Blizzard !
I see it’s been 2 years there is this bug and it is still not fixed. Can you please fix it, it makes the game unplayable for every macos player ! :cry:
