Solution 1Recommended

Disable Hardware Graphics Acceleration and Test in Safe Mode

Running Office in Safe Mode can help determine if the visual glitches are caused by add-ins or the hardware graphics acceleration rendering engine.

Office applications use hardware acceleration to improve performance, but this can sometimes conflict with your graphics card drivers, resulting in overlapping text and artifacts.

1
Launch Office in Safe Mode

Press the Windows key + R to open the Run dialog. Type 'winword /safe' (without quotes) and press Enter to launch Word in Safe Mode. Check if the screen artifacts still appear when you move your mouse.

2
Access Advanced Options

If the issue does not occur in Safe Mode, open Word normally. Go to File > Options > Advanced.

3
Disable Hardware Acceleration

Scroll down to the 'Display' section. Check the box for 'Disable hardware graphics acceleration' (if available in your version). Click OK and restart the Office application.

Disable Hardware Graphics Acceleration and Test in Safe Mode
Missing Option in Newer Builds: In some recent builds of Office 2021, the option to disable hardware graphics acceleration has been removed from the user interface. In this case, proceeding to a full repair is recommended.

Frequently Asked Questions

Why do screen artifacts only happen in Office 2021 and not other apps?

Office applications use a specific hardware graphics acceleration engine to render interface elements and text. If there is a compatibility issue between this engine and your system's graphics configuration, glitches will be isolated to Office programs while other Windows tools function normally.

Will updating my graphics drivers fix overlapping text in Office?

Updating graphics drivers is a common first step for display issues, but if you have already updated them and the text still overlaps when moving the mouse, the problem likely lies within corrupted Office installation files or its internal graphics acceleration settings.

What should I do if the Microsoft Uninstall tool doesn't resolve the issue?

If a complete removal and reinstallation using the Microsoft Uninstall tool fails to fix the artifacts, the issue might be a deep-rooted bug in your specific Windows build and Office combination. You may need to contact Microsoft Support for further investigation, or switch to a stable alternative like WPS Office.
