How to Fix Microsoft 365 Display Glitches by Disabling Hardware Acceleration
Question details
Users are experiencing graphical anomalies in Outlook and other Microsoft 365 apps and need to disable hardware acceleration, but the option is missing from the application interface.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Using Microsoft 365 applications like Outlook when graphical elements fail to render correctly.
- Observed behavior
- Graphical glitches, screen tearing, or display anomalies appear in the application interface, and the in-app option to disable hardware graphics acceleration is no longer available.
Before making changes to your system settings or the registry, ensure your graphics drivers are fully updated, as outdated GPU drivers are a primary cause of display glitches in Office applications.
Disable Hardware Acceleration via Registry Editor
Since Microsoft removed the UI toggle for hardware acceleration, you can force-disable it for all Office 16.0 apps via the Windows Registry.
Editing the registry applies the change across the entire Office suite. Please proceed carefully and follow the exact paths, as incorrect registry modifications can affect system stability.
Close all running Microsoft Office applications, including Outlook running in the background.
Press the Windows key + R, type 'regedit' in the Run dialog box, and press Enter to launch the Registry Editor.
Navigate to the following path: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common.
Right-click the 'Common' folder, select New > Key, and name the new key 'Graphics' (if it does not already exist).
Right-click inside the Graphics key, choose New > DWORD (32-bit) Value, name it 'DisableHardwareAcceleration', and set its Value data to 1. Restart your computer.
Force Power Saving GPU via Windows Graphics Settings
Assign a specific Office application to use the basic render driver, bypassing problematic hardware acceleration directly from Windows.

Frequently Asked Questions
Why did Microsoft remove the hardware acceleration setting from Office?
Microsoft has been transitioning Office applications to use modern graphics rendering engines automatically. To streamline the user experience, they removed the manual toggle from the standard user interface, relying on the operating system to manage GPU resources.
What does hardware acceleration actually do in Microsoft 365?
Hardware graphics acceleration uses your computer's Graphics Processing Unit (GPU) to render user interface elements and animations, offloading work from the CPU to make applications run smoother. However, incompatible or outdated GPU drivers can cause graphical glitches.
Will disabling hardware acceleration slow down my computer?
Disabling it forces the CPU to handle graphical rendering for Office applications. On modern processors, you likely will not notice a performance drop in everyday document editing, though heavy PowerPoint animations might run slightly less smoothly.
Do I need to restart my computer after editing the registry?
While a full computer restart is the most reliable way to apply registry edits, simply closing and restarting all Microsoft Office applications (including background processes) is usually sufficient for the DisableHardwareAcceleration value to take effect.
