@Friz64 any idea on how to fix?

Ouch, sorry about this. No idea why my PR would cause this. I unfortunately can't debug this by myself as I don't have access to appropriate hardware at the moment. Best I can do right now is to do some research, in the hopes that I find something useful.
But what we can always do is to put a #[cfg(not(target_os = "macos"))] over the _window variable in the RawHandleWrapper, so that the PR is essentially negated on macOS. It wouldn't be elegant, but it would work.

I'm getting this when setting RUST_LOG=debug cargo run --example sprite:

(it hangs from here, with no more info logged)
It looks like it's hanging before it creates the next surface texture after the previous was presented. After checking out the main branch from a week ago, we should additionally have the following logs after Presented. End of Frame before exiting the program:

Odd. It seems the Arc in WindowWrapper/RawHandleWrapper does eventually get freed, so the winit::Window is still being dropped, but dropping it later is somehow not working properly?

I'm a bit new to using a debugger, but it seems to be blocking on a Condvar?
It occurs within TaskPool::scope_with_executor_inner:

So it appears that something is not waking up the main thread. Perhaps the window Arc is never being dropped because something else made a copy of it, but the event loop depends on it being dropped?

There are probably better ways to debug, but I tested with this:
impl Drop for RawHandleWrapper {
fn drop(&mut self) {
println!("Drop RawHandleWrapper: {}", Arc::strong_count(&self._window));
}
}And something similar for WindowWrapper.
That shows a drop of a RawHandleWrapper with a ref count of 1. So it seems the winit::Window should be closed at that point.
I'm not familiar enough with macOS APIs to know if there's any macOS-related reason this might happen.

Ah. It looks like the drop impl for the WindowWrapper is called on the main thread, while the drop impl for the RawHandleWrapper is not.
So it's probably an issue that happens when the winit::Window is dropped on a thread other than the main thread.

On macOS, Drop for winit::Window uses https://docs.rs/objc2-foundation/0.2.0/objc2_foundation/struct.MainThreadBound.html Apparently.
On Drop, the inner type is sent to the main thread’s runloop and dropped there. This may lead to deadlocks if the main runloop is not running, or if it is waiting on a lock that the dropping thread is holding. See run_on_main for some of the caveats around that.

Yeah. it looks like the worker thread is hanging in icrate::Foundation::additions::thread::MainThreadMarker::run_on_main. (In lldb, the thread command lets you list and change threads.)
While the main thread is blocked on

So I guess bevy is blocking the thread running EventLoop::run, which is a problem on platforms like macOS?

Can this now be closed after #13236?
