I have been experiencing severe performance issues with Adobe InDesign recently, and had hoped that the 16.2.1 release would resolve them. Unfortunately the issues persist. The application regularly stops responding for 15 - 45 seconds at a time with the following type of interactions:
Clicking an input field (ex. Font size) to adjust a setting
Double-clicking a Page / Master Page to change the active page.
Adjusting any settings in Preferences
I have taken the following steps to try and address the issue, with no success:
Uninstalling all Creative Cloud services, and re-installing
Manually deleting all preferences
Resetting Preferences via Shift / Command / Control / Option shortcut
Re-validating all activated fonts, and removing any that have any warnings or errors
Disabling GPU performance
Disabling 'Type Contextual Controls'
Disabling all Pre-Flight features
NVRAM / SMC Reset
Nothing has resolved the issue, which persists throughout InDesign regardless of whether I am editing an existing document or creating and working with a new document. I'm at my wit's end as InDesign is essential for my daily workflow. Below is a breakdown of my system configuration.
