Mac M1 rhino 7 problem shapes of colors in workplan

While rotating or moving I have this random shapes of color in my workplan. A problem that I have in each view, it disappear when I zoom in or out. Obviously this is not a surface !
I use Mac M1 and rhino 7.11 , on my Pc with Rhino 7 I do not have this problem
