Update Adobe Acrobat to the Latest Version
Installing the latest patches often resolves user interface rendering bugs, such as the blank white box during redaction.
Adobe frequently releases patches to fix Chromium Embedded Framework (CEF) rendering issues, which are often the root cause of blank dialog boxes in Acrobat.
Launch the Adobe Acrobat application on your computer.
Navigate to the top menu bar, click on 'Help', and select 'Check for Updates' from the dropdown menu.
Follow the on-screen prompts to download and install the latest version (ensure it is version 21.07.20091 or newer).
Once the installation is complete, restart your computer to apply the changes completely.
Test with a Different PDF and Verify Security
Determine if the issue is isolated to a specific corrupted or secured file rather than the application itself.
Repair Installation and Manage CEF Processes
Fix corrupted application files or temporarily bypass the CEF rendering glitch by managing background processes.

Frequently Asked Questions
Why does Adobe Acrobat show a blank screen when I use redaction tools?
This is typically caused by a glitch in the Chromium Embedded Framework (CEF) processes that Adobe Acrobat uses to render web-based dialog boxes and user interface elements. Outdated software or corrupted cache often triggers this.
Does ending Adobe CEF processes permanently fix the blank box issue?
No, ending the Adobe CEF processes via Task Manager usually only provides temporary relief for that specific session. Updating the software to version 21.07.20091 or newer is the recommended long-term fix.
Can document security settings cause the redaction tool to fail?
Yes. If a PDF is secured with a permissions password that restricts editing or document assembly, the redaction tools may be grayed out or fail to apply properly. Always check File > Properties > Security to verify your permissions.
