How to Fix Gray Blocks Covering Text in Word for Mac
Question details
The user needs to fix an issue where gray blocks with grid lines unexpectedly cover text and tables in Word for Mac documents.

- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Editing or viewing multiple documents that were generated from the same document template.
- Observed behavior
- Gray blocks with grid lines appear over text and tables, obscuring the content. Reinstalling the Office suite does not permanently resolve the issue.
Verify whether the issue occurs in all new blank documents or only in documents created from one specific template, as this helps isolate the root cause.
Test and Recreate the Corrupted Template
Because the gray blocks only appear in documents generated from a specific template, the template file is likely corrupted and needs to be isolated and replaced.
Document corruption can cause severe rendering issues like gray blocks or grid lines over text. If reinstalling Microsoft Office didn't help, the problem is embedded within the document structure or the specific template (.dotx) used to create these files.
Open Word for Mac, go to File > New Document, and type some sample text. If no gray blocks appear, your base Word installation is fine, confirming the issue is isolated to your custom template.
Open a document experiencing the issue. Delete any sensitive or confidential information, then save a copy of this document to your Desktop.
Open a completely new blank document. Manually copy the non-corrupted text from your old template and use Edit > Paste and Match Formatting to ensure you do not carry over the corrupted formatting. Save this new file as a Word Template (.dotx).

Update macOS and Microsoft Word
Certain rendering glitches, especially on newer operating systems like macOS Big Sur, can be resolved by installing the latest patches.
Try WPS Office for Mac for a Glitch-Free Experience
If Microsoft Word continues to display gray blocks and rendering errors, consider switching to WPS Office. It is a highly compatible, free, and lightweight alternative that processes complex Word templates seamlessly on Mac without visual glitches.
- 1. Download WPS Office: Visit the official WPS Office website and download the free Mac installation package.

- 3. Open Your Template: Drag and drop your existing .docx or .dotx files directly into WPS Office to continue your work without formatting loss.

Frequently Asked Questions
Why do gray blocks appear over my text in Word for Mac?
This rendering issue is typically caused by a corrupted document template or a compatibility glitch between the specific version of Word and your macOS version (such as Big Sur).
Will reinstalling Microsoft Office fix the gray blocks issue?
Reinstalling Office usually does not fix this issue permanently because the problem stems from the underlying document structure or template file, rather than the application software itself.
How do I safely share a corrupted document for troubleshooting?
Save a copy of the problematic document, manually delete any personal or confidential information, and upload the file to a secure cloud service like OneDrive or Dropbox to generate an anonymous sharing link.
