The only time this happened to us is if we had open GL enabled for 2d drawing. Disable (in preferences) and wait to enable it once we have 8.1. If that is not the case, ie, you allready have it disabled, I don't have a clue. BTW, does anyone know if open GL, for 2d, does now work in 8.1? We have not received the update, - checking the mail twice a day.
yes - i have openGL enabled for 2D - on a big projects it is really a worthwhile timesaver.
i don't get the 'white-out' when i'm not using it, nor do i get it with openGL enabled for 2D on a dual 867 G4 tower, (hence the title: 'openGL on mac powerbook'!!). the difference is that the powerbook has an ATI mobility card, and the tower an nvidea geforce 4
i am using 8.1, so i guess that you won't be in luck when you get your copy.
