i guess, this is definitely not a system configuration far beyond any normality in the graphic designworld. apple produces a very small number of machines, where ADOBE has the honourful job to make their software compatible with.
WHY – DON'T – THEY ?!
everytime i am moving around in my AI-files, i get those AWFUL horizontal lines dropping from the top of the screen. it makes me simply crazy, because it covers the whole canvas.
switching the gpu-usage of AI off IS NO SOLUTION. because the scrolling/zooming-behaviour of AI gets even more awful!
where is the update to fix this incredible bug ?! i pay 60€ every month ... and 21.000 people work at ADOBE ... a new AI incompatible with standard actual apple hardware should NEVER PASS QUALITY control and be able to leave the house.
