Hi lubby1010,
I’ve tried this at my end to check if the same behavior will occur if a PowerPoint file will turn into a blank page when it’s not the active application and it didn’t reproduce the same result. The contents of the file are still visible as I've replicated the concern.
For us to identify if the issue is with the file or with the PowerPoint app itself, we’ll try to perform some troubleshooting steps. Just to confirm, does the issue occur on the other PowerPoint files saved on your PC? Do you get the same observation when opening it on a different computer? Can you confirm the build and version of PowerPoint that you're using? Click this link for the steps to know how.
As an initial step, I’d recommend opening PowerPoint in safe mode. This will help us troubleshoot the issue accordingly. Click this link for the steps. As soon as it’s already on safe mode, open the PowerPoint file and another application on your PC, then see if it will be blank as you select or click the other application.
If the issue doesn't persist while on safe mode, you can use the instructions below to identify which add-in is causing it to happen:
- Click File > Option > Add-ins, then click Go in the Manage: COM Add-ins.
- Clear the checkbox if you'll see any add-ins, then disable them.
- Close the PowerPoint app and relaunch it after.
- Check if you'll still get the same behavior.
Please respond to this thread to let me know how the issue progresses. Similarly, if you have more questions, please inform me by replying to this post.
