Extreme lag - Adobe Reader DC on Windows 11

Hello,

I work in a large multinational and we proofread documents using comment tools on Reader DC with our own custom stamp palette for speed. We recently migrated to Windows 11 and since then, our team has experienced extreme lagging issues. The program seems to start out ok and its performance slowly deteriorates (especially for large documents or when working with multiple PDFs), to an almost stand-still at times. Here's a description of some of the issues:

- When applying a new stamp, sometimes it takes 2-5 sec after clicking for the stamp image to "stick" on the page.

- When using the pencil tool, most of the time you must hold the mouse button down for 2-3 sec. for the drawing to start showing, otherwise it only makes a dot or else just a straight line from the point you started the drawing to where the cursor ended up.

- When switching between documents/tabs, it can take anywhere from 5 to 20 seconds for the new document to display and sometimes the software freezes with a turning wheel and a message saying "(not responding)".

Our IT team tried several steps:

- Changing security settings as described in this community post: https://community.adobe.com/t5/acrobat-reader-discussions/adobe-acrobat-reader-is-incredibly-slow-amp-keeps-hanging/td-p/12222566

- Uninstalling/reinstalling Reader DC;

- Manually uninstalling/wiping out all registry files and reinstalling Reader DC directly from the Adobe official website and installing all latest updates and patches, then reimporting custom stamps;

- Testing with Acrobat Pro on one machine (for a coworker).

Some of these fixes yielded an initial improvement, but Reader (and Acrobat Pro) quickly deteriorated again after a few minutes/hours of work. Reader DC is our team's preferred tool for proofreading due to its better tools and well-designed interface, and we use it for over 90% of our work. As this remains an issue, we have been using a similar alternative PDF-editing tool.
