Hello,
today I updated to Cura 4.0.0 on my Mac OSX High Sierra V10.13.6, 2.8 GHz Intel Core i7 (2011), 16GB RAM.
But Cura4.0.0 is incredibly slow. I cannot work with it. I made a video where you can see how lazy Cura 4.0.0 acts on scrollbars, or 3D view changes, rotation of 3D objects:

Why is cura so slow??? I cannot use it this way!
Thanks fpr any help...
