Hi Dev
Hope you are doing well and sorry for the trouble. As described commenting PDF documents became laggy.
Is this a behavior with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. If the file is stored on a shared network/drive, please download it to your computer first and then try again.
What is the version of the OS and the Adobe Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the latest version 21.07.20091 installed. Go to Help > Check for updates and reboot the computer once.
Also, please try to reset the Acrobat preferences as described in the help page https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-defau... and see if that works for you.
You may also try to create a new test user profile with full admin rights or enable the root account in Mac and try using the application there.
If it still doesn't work, please share the logs of the affected machine so that we can narrow down and isolate the issue
For Mac: Please collect the logs using the log collector tool as desscribed in the help page https://helpx.adobe.com/creative-cloud/kb/cc-log-collector.html
For Windows: Please download the procmon tool here https://docs.microsoft.com/en-us/sysinternals/downloads/procmon run the procmon tool and regenerate the issue and collect the logs.
Please share the collected logs using the Document Cloud service as described here https://helpx.adobe.com/document-cloud/help/sharing-pdfs.html
Also please share the afftected/sample PDF file and a small video recording of the issue so that we can check it at our end.
