It was only processing a single event per call. The docs say > Fetches all the events that are pending, calls the callback function > for each of them, and returns. which suggests that was incorrect.
This is the same behavior as with WindowProxy::wakeup_event_loop in
previous versions.
Unfortunately, `EventsLoop::interrupt` is also the recommend way to exit
a `run_forever` loop from within the event handler callback. Pushing an
extra event on the queue in that case is simply wasteful. Changing this
would require a refactor taking one of two possible forms:
1. Add a method *in addition* to interrupt intended for waking up the
event loop
2. Add a return type to the event callback like
enum Continue { True, False }
which would be used in lieu of the atomic interrupt flag.
This makes is possible for consumers to use cargo [replace] with the latest Glutin.

Thanks for the review and the recent refactoring work :) |
For X11 interrupt, we can just use the root window which doesn't require taking a lock to find.

poll_eventsactually drains queue as the documentation suggestsEventLoop::interruptactually wakeup the event loop. Previously it would just raise a flag without allowingrun_foreverto spin. This is the same behavior as the oldWindowProxy::wakeup_event_loopmethod.Unfortunately,
EventsLoop::interruptis also the recommend way to exit arun_foreverloop from within the event handler callback. Pushing an extra event on the queue in that case is simply wasteful. Changing this would require a refactor taking one of two possible forms:event loop
which would be used in lieu of the atomic interrupt flag. With the return value here, interrupt would only be needed from other threads.
At any rate, that's out of scope for this PR. Should I open a ticket discussing this API issue?
