How to Fix Microsoft Word 365 Slowness When Using Ink
Question details
Microsoft Word 365 experiences significant lag and slowness when working with documents that contain ink, particularly during scrolling or zooming after extended editing sessions.

- Product
- Microsoft Word 365
- Device & OS
- Windows
- Scenario
- Editing, scrolling, or zooming in Word documents that contain digital ink or handwritten notes for extended periods of time.
- Observed behavior
- The application becomes increasingly slow, unresponsive, or laggy when handling ink, whereas other applications like OneNote remain largely unaffected.
Save your current work and verify that the slowness is isolated to Word by checking if the same inking performance issue occurs in OneNote, Excel, or PowerPoint.
Update Office and Run Word in Safe Mode
Starting Word in Safe Mode bypasses add-ins that might be causing rendering issues with ink, while updating ensures you have the latest performance patches.
Third-party add-ins or outdated Office components are common culprits for rendering lag. By updating the software and testing in Safe Mode, you can isolate the root cause.
Open Microsoft Word, go to File > Account > Update Options, and select 'Update Now' to install the latest version.
Press the Windows key + R to open the Run dialog. Type 'winword /safe' and press Enter to start Word without add-ins.
Create a new document, draw some ink, and test scrolling and zooming to see if the slowness persists.

Perform an Online Repair of Office
If Safe Mode doesn't resolve the issue, repairing the Office installation can fix corrupted files causing the ink rendering lag.
Perform a Windows Clean Boot
A clean boot helps determine if background software or third-party services are interfering with Word's performance.
Try WPS Office for Smooth Document Editing
If Microsoft Word continues to lag when using ink or navigating complex documents, consider switching to WPS Office. It provides a lightweight, highly compatible, and seamless editing experience for all your document needs without the heavy resource usage.

Frequently Asked Questions
Why does Microsoft Word only lag when I use ink?
Word handles digital ink as complex graphic objects. Rendering these objects, especially after extended editing sessions or zooming, consumes significant memory and processing power, which can lead to application lag.
Will an online repair delete my personal Word documents?
No, performing an Online Repair of Office only fixes the core program files. Your personal documents, including those containing handwritten notes or ink, are completely safe and will not be deleted.
How do I check my current Word version to see if it needs an update?
To find your specific Word version, open the application, click on 'File', and select 'Account'. The version and build number will be displayed on the right side under 'About Word'.
Can I disable hardware acceleration to fix ink slowness?
Yes, hardware graphics acceleration can sometimes conflict with your computer's display drivers, causing slow rendering. While modern versions of Office have removed this exact checkbox, updating your graphics drivers or tweaking registry settings can achieve a similar troubleshooting effect.
