Here I am again salvager , On Kerbin, low altitude, the shading problem is the same: BUT! at Minmus, everything is OK, no shader problem, and the shadow of the ship is under the ship, correclty :0 but, in the same game session, I flew on MUN, again, and: this, in the same game session where MINMUS was "OK" I dont understand... Minmus is much lighter than MUN? After, I've played on Fullscreen (no windowed) and I have some random crash... mac crash report: https://www.dropbox.com/s/yz126k8im3izlav/KSP_crash.txt?dl=0 - - - Updated - - - ...and I repeat , until today, I played without problems for three years on a macbook 2008 ...
