Description

Not sure whether this is intended, but it doesn't seem so based on what I've read of the documentation. Even though I call request_redraw on every RedrawRequested event, I don't receive any more RedrawRequested events unless I also call request_redraw from fn about_to_wait.

This is a wgpu app using winit f3fb2fe and wgpu 28.

Device and iOS version

iPad Pro M5 13-inch running iPadOS 26.3
