Runaway CPU in Acrobat DC Pro 2020.006.20042 (Mac OS X 10.15.4 - Catalina)

When I open a PDF file in Acrobat DC Pro, CPU usage rises to over 95% and stays there as long as the window is in focus. If I bring another application window into focus (such as Chrome, where I am writing this now), CPU usage drops to below 10%. However, if I bring the Acrobat window back into focus, the CPU pegs again. I am doing nothing in Acrobat. I just opened a document, and I'm reading the first page. CPU usage remains at 95%+ as long as the window stays in focus.

This has been happening for over a week. I have rebooted the system several times in the interim, but the issue persists. Here is some info on my machine:

Any help would be appreciated.

    Hi Kevin

     

    Thank you for sharing the logs. Please give us some time to get it checked, we will share the update soon.

     

    In the meantime, please try to reset the preferences to default as described here https://community.adobe.com/t5/acrobat/how-to-reset-acrobat-preference-settings-to-default/td-p/4792082?page=1  and see if that makes any difference.

     

    If it still doesn't work, please create a new test user profile or enable the root account in mac https://support.apple.com/en-in/HT204012 and try using the application there and check for the issue.

     

    Keep us posted with the results.

     

    Thanks for your time, patience and cooperation

     

    Regards

    Amal


    Hi Kevin,

     

    We have got the update from the engineering team.

     

    Please try to disable page caching by unchecking the option "Use page cache" in Edit > Preferences > Page Display > Rendering.

    Btw the solution of Amal worked for me on Windows 11, too. Thanks!

    Hi kevinh

     

    We are sorry for the trouble and the experience.

     

    As described the Acrobat Dc is using most of the CPU  storage, it may be due to some processes running in the backend and thus consuming high CPU storage. Since you already have the latest version of the application. Please try the following steps and see if that helps:

     

     

    Let us know how it goes

     

    Regards

    Amal

    Hi Amal,

     

    Thanks for looking into this. I disabled the page cache and used Acrobat Pro DC for several days. The change appears to have resolved the issue. The CPU no longer spikes while using the program.

     

    Thanks!
