After the last update, the following things no longer work properly:
1. CC Libraries
(Crashes and shows either a reduced or enlarged section of the library and is no longer usable. Only a program restart helps ... short term! see screenshot 1. the bug was already in Illustrator!)

1. edge smoothing! (Not only since the update): ... Does not work properly for quite some time! 2.1 Completely covered areas, lines and graphics have a slight contour due to the edge smoothing and become minimally visible (although these would actually be invisible and not visible in print) or form minimally soft edges, or corners where there are none! (see screenshot 2) 2.2 Frames with effects and in which images are loaded whose outer edges are 100 percent transparent, form fine gray outer lines on the outer edges where there are none!
2. effect & effect preview: no longer works properly with texts and shreds them after scaling or makes them invisible! A problem which I never had before and what worked wonderfully before the update. (S. Scrrenshot 3)

In addition, as an addition bugs in Íllustrator with 3D extrusions and invited images on it! Bugs with Adobe RAW: Zoom Scollrad works no longer or only stuttery!

Dear Adobe team, what is going on? The whole thing costs a lot of time, a lot of money and nerves ... infinite nerves!!!!!!!!! It's starting to remind me of QuarkXpress!
