Wonky External Display After Opening Certain Apps on Primary Display of iPad Pro M4

When I open certain apps, such as Notability, the external display goes into a strange state until I toggle "allow display mode changes."

This two-minute video shows the behavior.

Does anyone know what is going on here?

iPadOS 18 glitch with Ext. Display Device Stats: • iPad Pro 11” 256GB with M2 chip • ViewSonic 32” 1080P monitor (HDMI) • Acer adapter (USB-C to HDMI, USB-C, USB-A ports) I’m beyond frustrated with Apple’s latest iPadOS 18 update. Here’s the situation: On September 16, 2024, at 1:30 PM ET, I decided to download iPadOS 18, the latest version just released to the public. Within 2–5 minutes, I ran into a glitch. My iPad Pro had been working perfectly with my external ViewSonic 32” 1080P monitor using an Acer adapter (USB-C to HDMI) while running iPadOS 17.4.1 for over two months. All ports were being used: one for power, a USB-A port for my wired keyboard, and another for my Apple Magic Trackpad. The issue: After the update to iPadOS 18, when I move an app (let’s call it App #1) to the external monitor, it works fine. I can open a second app (App #2) on the iPad Pro’s main display without issue. But, when I close App #2 on the iPad, App #1 unexpectedly jumps back to the iPad display, forcing me to drag it back to the external monitor and resize it each time. This glitch doesn’t happen the other way around—closing App #1 doesn’t affect App #2 on the iPad display. I tested multiple apps, including Apple’s native apps, and the same problem occurs across the board. I contacted Apple Support (always a joy), and they had me toggle Stage Manager off and on, which temporarily resolved the issue… until it didn’t. The glitch returned as soon as I ended the chat. This never happened on iPadOS 17.4.1. Apple’s next suggestion? Reset the iPad to factory settings. Sure, that might solve it, but I’m not thrilled about setting everything up from scratch—especially having to re-add all my bank cards, which is a hassle if you’ve got more than one. Has anyone else experienced this issue? Any helpful suggestions are welcome!
