3. Attempt to scroll with scroll wheel

Settings list scrolls

Either:

Worked around by turning on this windows setting:

Most likely it is the regression introduced in WinUI3 v1.6

Unfortunately, the trick here is that Terminal is not using WinUI 3. The only version of WinUI we use is the one that comes with the OS.

Sorry for the misleading comments then :) Interesting that the same workaround works

Thanks for filing! Sounds like this may be a duplicate of #9340. Mind taking a look through the thread and seeing if it helps /? Looks like this was a proposed solution: #9340 (comment)

I don't use that third party app, and can reproduce this on a clean Vm.

I'm sorry, I think we got our wires crossed. This is a Windows platform limitation due to how WinUI 2 hosts XAML content in Win32 applications. It should reproduce in the roughly one other application ("perception simulation input", lives in system32) that uses WinUI 2 Islands. It looks like Facebook authored a workaround for this issue in React Native, but we're not likely to take it here in Terminal.

The nitty gritty is that the input site XAML uses to collect input is neither focused nor active when the Terminal window is.
