Question

Gray overlay blocking Acrobat

  • June 12, 2026

When Acrobat Pro opens, within 10 seconds a darkened background and a blank gray modal dialog/overlay appears in the center of the screen. The dialog contains no text, buttons, loading icon, or close option, and it blocks all interaction with the application. I can still see the Acrobat interface dimmed behind it.

The only way to close Acrobat is through Task Manager. Restarting the computer, uninstalling and reinstalling Acrobat, and trying common keyboard shortcuts such as Esc, Alt+F4, Enter, and Alt+Space have not resolved the issue. The problem appears shortly after opening a PDF, or even just opening Acrobat without opening a specific PDF.

I have attempted the solution offered here without success: https://community.adobe.com/questions-12/acrobat-white-box-after-install-1505692

System: Windows 11. Acrobat Pro installed through Adobe Creative Cloud. Latest updates across the board.

    Update:

    I have done some further testing:

    • Created a new local Windows user account and tested Acrobat Pro there. The same issue occurred.
    • Deleted/renamed system-wide Adobe cache under C:\ProgramData\Adobe. No change.
    • Checked Event Viewer while starting Acrobat Pro and then force-closing it through Task Manager. I did not find any relevant Error messages.
    • Checked Task Manager / wait chain analysis, but found nothing useful.
    • Looked for possible overlay software. The only relevant item I found was NVIDIA Overlay via NVIDIA App. Turning NVIDIA Overlay off changed nothing.
    • For testing, I have had no other Adobe applications installed and Creative Cloud is not installed.
    • Uninstalled Acrobat pro and installed Adobe Acrobat Reader, which works normally. I was able to install Reader, sign in, open and load PDFs without any issue. The grey/blank overlay problem does not occur in Reader.

    For context, the issue first appeared after I dragged/dropped around 20 JPG (~1MB each) files into Acrobat Pro to convert/combine them into one PDF. Acrobat appeared to hang during that process, and I may have interrupted or cancelled it.

    Hi ​@22865830pl21,

    Sorry for the troubled experience, and thanks for reaching out.
    Could you please check this discussion: https://adobe.ly/4v4Yu1M? Is this the issue you are experiencing as well?

    If that is the case, this is a known issue and has already been reported to the product team.

    Also, could you share the following details, so we can escalate this to the product engineering:

    • Check for any pending updates. To check for updates, launch Acrobat > Help > Check For Updates.

    • Acrobat version. To check, launch Acrobat > Help > About Adobe Acrobat.

    • A short video of the issue

    • Operating system name and version.

     

    These details will help us identify the root cause and help us escalate the issue internally to the product team.

    Hi Tariq,

     

    Thank you for your reply.

     

    The discussion you suggested is not relevant; I am not experiencing these problems in conjunction with signing - I can not open and use the app at all, really. I did, however, try your suggestion to disable page cache from that thread, without success. 

     

    With regards to the details you asked for:

    • I have uninstalled and reinstalled Acrobat (through CC and the Enterprise version*) and Creative Cloud several times, so all versions are the latest, and no updates are pending.
    • Acrobat version: 2026.001.21662
    • I can’t easily make a video, but I feel that the problem is well enough described in my original question.
    • OS Name: Microsoft Windows 11 Home
      Version: 10.0.26200 Build 26200
