Obects turn into line boxes

Objects turn into line boxes when I right click on mouse to rotate object for viewing. Did not always do this…
How can I stop this from happening?

You could set dynamic redraw target frame rate to something lower under Tools » Options » View.

@cadgem, you probably have enabled the BBox box display in the current display mode. This can be changed from the display tab:

or in the _Options for every display mode:


That was it, BBox Display .Thanks Clement…
