app.AppearanceChanged event bug?

According to the documentation, the AppearanceChanged event is triggered when a user switches between light and dark mode, or when the accent colour changes.

However, this event is not triggered when I change the accent colour. However, it is called when I switch between light and dark mode.

This issue can easily be reproduced using a basic desktop app containing one statement with a breakpoint in the App.AppearanceChanged event.

The configuration is Xojo 2026.21 on Tahoe 26.6.2.

Is this a bug, or am I missing something?

This definitely used to work and appears to be a bug now.

The event fires in macOS 15.7.9 but not in 26.6.2 with the same application.
