**Debug log**

maybe later.

**Upload VM**

I am running Windows 11 23H2 aarch64 in UTM

**Here is a demo video of the bug**

First bug: Abnormal display of virtual machine contents in UTM.

This bug also exists on iPadOS 15 when using AirPlay for casting. Maybe it's similar to this issue #5724

Temporary workaround: open UTM in the iPad Pro and run the VM, then transfer it to the external screen.

Second bug: If you run UTM alone, the mouse cannot be captured under external screen. Or maybe it's locking the mouse in the UTM VM, and you can't get it out.

Third bug: running two apps in the external screen, UTM can capture mouse movement, but it will be shifted.
But you can resize the app window, and UTM will adaptively adjust the VM resolution as well
