Selection display

on Rhino6, in “shaded mode” display, when i select a polysurface, normaly every edge pass to yellow, but on my V6, every edges deseppear, is it a rhino bug or a hardware bug of my computer? maybe a bad pilot of graphic card?

Hello - thanks for the report… that does not happen here, so far. Are the display modes ‘default’?


in fact, i import display modes of my rhino V5…
in V6 default display mode, it’s ok…
