Redraw Requested not issued for glutin examples (winit examples too?) until at least one other event has been issued.

The glutin examples for some reason don't draw until you've moved the mouse or pressed a key at least once. I suspect this is a winit bug. Found while testing out #925 .

This is probably related to an issue I see in EL 2.0 on macOS (legacy examples work fine in that regard).

Most examples work like this: I press the window's close button - nothing happens - I move the mouse slightly - window closes.

I suspect returning ControlFlow::Exit only really causes the loop to exit after another event has been received. Maybe there is a code ordering error in the event loop logic.

Is this running on winit master? Because it sounds like the kind of bug I expected from #982, but didn't show up for me in testing.

[goddessfreya]

Yes, was done against master.

@zegentzy On what platform(s)?

If Linux/X11, did #982 cause this (i.e. commit 29e2481) or is the issue also visible with the commit before (3555de1)?

[goddessfreya]

Issue was present before #982, on x11. I'm afraid I lack time to git bisect this issue.

I only discovered this after setting Poll to Wait in my logic.

I thought manually calling request_redraw after catching it from an EventsCleared event would work, but turns out it doesn't (for Wait; Poll has been working correctly for me with that approach).

Have any of the various bugfixes we've made in the past six months or so addressed this?

[kettle11]

I ran into this issue today when experimenting with Glutin examples.

[kchibisov]

I think this is fixed in some form.

Though, it'll be fixed once #2900 lands.
