What is this new extruded body display

Suddenly the display of extruded bodies changed on my computer (Mac M1)

Please help and I hope it is not a ““New Feature”” that would be a huge way back

On the first screenshot you’re showing move/rotate tool nothing common with extrude.

On the second it seems you’re in Wireferame mode. (Shaded is the normal mode)

Thanks. I was not aware of the wireframe view, I do not know how I did activate it.

About the picture with move tool, I’m aware of the tool selected, I wanted just to pinpoint the fact that I had those two wireframes behaving like a solid.
