‘Shadow’ Apps

Thank you for clarifying the device you’re using, Griffkev. 

With the updated information it sounds as though you’re seeing the grayed out squares when access the app preview screen that displays opened apps as outlined in the following article. 

Close an app on your iPad

Are you noticing the squares appear where there was an app preview showing previously? If so, does the gray square appear if you return to the app preview screen?

You mentioned that your iPad is fully updated. To confirm, you’ve updated to iPadOS 15.0.2?

Update your iPhone, iPad, or iPod touch

 If so, the next step would be to contact Apple. You can find their contact details online via the Get Support website. 

Have a great day. 

Hello Griffkev, 

It sounds as though you’re asking about the grayed out squares/rectangles on the display of your Mac. Apple Support Communities is a great place for help! To clarify, where are you seeing these appear? For example, are you using a specific application or do they appear elsewhere? What steps do you take immediately prior to these appearing? 

If you restart your Mac do these remain? If you’re unsure, you can find the steps for restarting in the following article. 

Log out, sleep, wake, restart, or shut down your Mac

We look forward to your response!
