I was initially using `MessageReader<WindowResized>` in my system for my app but once my system grew to use more and more window events, I refactored to using `MessageReader<WindowEvent>` and matching on its variants. This is where I ran into the issue of the `WindowEvent::WindowResized` case never matching. When making this PR, I noticed `WindowEvent::WindowBackendScaleFactorChanged` and `WindowEvent::WindowScaleFactorChanged` had the same issue. # Objective Fixes #15268 ## Solution Instead of writing into `MessageWriter<WindowResized>`, `MessageWriter<WindowBackendScaleFactorChanged>` and `MessageWriter<WindowScaleFactorChanged>`, push into `bevy_window_events` where it gets sent to the `forward_bevy_events` function for syncing the messages. ## Testing I made local modifications to the `window_resizing` example to use a `MessageReader<WindowEvent>` instead of `MessageReader<WindowResized>` like so: ```rs fn on_resize_system( mut text: Single<&mut Text, With<ResolutionText>>, mut resize_reader: MessageReader<WindowEvent>, ) { for e in resize_reader.read() { if let WindowEvent::WindowResized(e) = e { // When resolution is being changed text.0 = format!("{:.1} x {:.1}", e.width, e.height); } } } ``` I ran this example on linux wayland.
