Hello there,

 

I recently discovered there's an issue with the combination of macOS Catalina, Illustrator (at least) and 4K.

 

  1. At full size the performance on 4K is horrible, while on HD it works as intended.
  2. When you size down the hole AI window on 4K, it improves the performance.
  3. When you check "Open at low resolution", performance will be okay at full size 4K (see video).
  4. When you select Apple RGB as color profile in the macOS preferences, performance will be okay (mine is a self-calibrating display so the calibration profile was active).
  5. Has nothing to do with GPU or UI scaling in the preferences.
  6. No issues with other applications yet.

 

 

I will follow up with specs.

Same behavior with current Illustrator 2020 (24.2.1).

I just changed my color profile in the preferences from my calibration profile to Apple RGB and that did the trick!


Adding to the list in the initial post.

 

Still, searching for a solution since I need to work on a calibrated view.
