PowerPoint Presenter View Bug on Window Resize (Office 2021)

Question

Hi all,

I'm facing a repeatable issue with Microsoft PowerPoint (Office Professional Plus 2021) on Windows 11.

When I launch a slideshow using Presenter View, everything works fine initially. But when I resize the PowerPoint window, specifically from maximized to normal (restored) view, the slide preview in Presenter View overlays itself, creating a ghosting or duplication effect.

Here’s a quick summary:

Issue appears even without external monitors.

Happens consistently when toggling from maximized to normal window state.

Using Office 2021 Professional Plus.

All Windows updates and graphics drivers are current.

Hardware graphics acceleration is enabled (disabling didn’t fix it).

I've tried:

Running PowerPoint in Safe Mode.

Resetting display scaling and resolution.

Toggling Presenter View on/off.

Disabling hardware acceleration.

No luck so far.

This looks like a rendering bug specific to PowerPoint 2021. Has anyone else experienced this? Any known fix or workaround?

Thanks in advance!

Hi @tariq kipkemei, 

Thank you for posting your question in the Microsoft Q&A forum. I really appreciate the level of detail you’ve provided and the troubleshooting steps you’ve already tried.  

I did some digging and found a similar discussion, although it was reported quite a while ago and on Microsoft 365 rather than Office 2021: PowerPoint Presenter View bug with Windows 11 - Microsoft Q&A .While it’s not an exact match, it does suggest that PowerPoint can occasionally run into rendering issues in Presenter View. 

At the moment, I couldn’t find any official documentation or confirmed fix for this specific scenario, and unfortunately, I don’t have the ability to replicate your exact environment. However, could you kindly try repairing Office using this guide: Repair an Office application - Microsoft Support  and see if that helps? 

If the issue persists, I strongly recommend sending feedback directly to the product team via PowerPoint > Help > Feedback > Report a problem.   

This ensures your report reaches the right team along with diagnostic details that can help them investigate. You can also share your feedback in the PowerPoint · Community, where similar cases are discussed and often picked up by the product team. 

I know this isn’t the definitive solution you were hoping for, and I truly appreciate your understanding that as a forum moderator, I don’t have the ability to modify or escalate product issues directly. I’ve searched extensively within my scope, but there’s limited information available at this time.
