- Product
- Microsoft PowerPoint
- Device & OS
- not provided
- Scenario
- Editing text or presenting slides in PowerPoint.
- Observed behavior
- PowerPoint text appears jumbled, with letters overlapping each other or failing to maintain normal spacing, making the content unreadable.
Before troubleshooting, check if the overlapping text issue occurs in all presentations or just a specific file, and save your current progress.
Run an Online Repair of Microsoft Office
Repairing the Office installation is the most effective way to resolve core application glitches causing text to render incorrectly.
Corrupted installation files or conflicting background updates can cause presentation formatting to break. Running the built-in Online Repair tool will reinstall core components without affecting your personal files.
Press the Windows key, type 'Control Panel', and press Enter. Navigate to 'Programs' > 'Programs and Features'.
Scroll down the list of installed applications, locate your version of Microsoft Office, right-click on it, and select 'Change'.
In the dialog box that appears, select 'Online Repair' (not Quick Repair) and click 'Repair'. Follow the on-screen prompts and restart your computer when finished.

Disable Hardware Graphics Acceleration
Disabling hardware acceleration forces PowerPoint to use software rendering, which can resolve visual glitches caused by display driver incompatibilities.
Test in Safe Mode and Check Printer Drivers
Running Safe Mode isolates add-in conflicts, while updating the default printer driver fixes background text layout calculations.
Use WPS Presentation for Flawless Slide Editing
If Microsoft PowerPoint continues to struggle with text rendering bugs, hardware acceleration glitches, or overlapping letters, consider switching to WPS Office. It provides a lightweight, highly compatible alternative that displays text beautifully without demanding heavy system resources.
- 1. Download and Install WPS Office: Visit the official WPS Office website and download the free installation package for your operating system.
- 2. Open Your Presentation: Launch WPS Presentation, click 'Open', and select your existing PowerPoint file to continue editing without text glitches.

Frequently Asked Questions
Why does my text overlap only when using specific fonts like Calibri Light?
This happens when the specific font file on your operating system becomes corrupted or is not properly cached by Office. Changing the font to a standard alternative or reinstalling the font family via Windows Settings usually resolves the glitch.
Can a printer driver really affect PowerPoint text spacing?
Yes. PowerPoint and other Office applications rely on the default printer driver to render on-screen text metrics and calculate slide layouts. An outdated, corrupt, or offline printer driver can severely distort letter spacing.
How do I know if a PowerPoint add-in is causing the text issue?
You can verify this by holding down the 'Ctrl' key while launching PowerPoint, which forces it to open in Safe Mode. If the text overlapping disappears in Safe Mode, a third-party add-in is interfering with the application.
