I set flow to ControlFlow::Wait in order to not waste CPU on doing nothing.
When application calls Window::request_redraw() I would expect RedrawRequest to arrive right away (after MainRequestCleared if there are queued events). Yet no ReadrawRequest is received until other events happen. Particularly if mouse and keyboard are untouched app would wait for ReadrawRequest indefinitely.

I tried to call Window::request_redraw() at different moments. Nothing helps. Then I found that using ControlFlow::Poll causes RedrawRequest to be received as expected, without any input.

Is it expected behavior? I couldn't find anything like this in the docs for ControlFlow.

Platform: Windows 10.
