Fix Microsoft 365 Copilot Chat Not Rendering Code Blocks Correctly
Question details
The user is experiencing a formatting issue where Microsoft 365 Copilot Chat fails to display code blocks with the correct visual layout and formatting.
- Product
- Microsoft 365 Copilot
- Device & OS
- not provided
- Scenario
- Generating or reviewing programming code within the Copilot Chat interface.
- Observed behavior
- Code blocks are rendered incorrectly, lacking the expected syntax highlighting, structured formatting, or background styling.
Ensure your web browser is fully updated to the latest version and verify if the formatting issue persists across different Copilot chat sessions.
Clear Browser Cache and Toggle Hardware Acceleration
Resolve visual rendering bugs by clearing cached data and modifying your browser's hardware acceleration settings.
Corrupted cache files or graphics rendering conflicts in the browser can prevent web applications like Copilot Chat from displaying formatted elements properly.
Open your browser (e.g., Microsoft Edge) and click the three-dot menu icon in the top-right corner to open Settings.
Navigate to the Privacy, search, and services section, click 'Choose what to clear', ensure 'Cached images and files' is selected, and click 'Clear now'.
Go to the System and performance tab in Settings. Toggle the 'Use hardware acceleration when available' switch to the opposite state (off if it was on, or vice versa).
Click the 'Restart' button that appears to apply the changes, then reload Copilot Chat to see if code blocks render properly.
Test an Alternative Browser or Edge Version
Determine if the rendering issue is isolated to your current browser version by testing in a different environment.

Frequently Asked Questions
Why does Microsoft 365 Copilot Chat sometimes fail to format code blocks?
Formatting failures are often caused by temporary server-side rendering bugs, corrupted browser cache interfering with web scripts, or incompatible browser extensions that disrupt page styling.
Can browser hardware acceleration affect web page rendering?
Yes, hardware acceleration offloads graphics processing to your GPU. If your system's graphics drivers are outdated or incompatible, it can cause visual anomalies, including broken text or missing styles in web applications.
How long does it take for Microsoft to fix Copilot rendering bugs?
Resolution times vary depending on the bug's complexity. Submitting detailed feedback with screenshots through the built-in reporting tools helps developers identify and patch server-side issues much faster.
