Yes. I am already looking into this + other flaky dinput tests that fail
in a similar way.
Turns out that on Windows dinput sometimes just drops key events injected
via SendInput() / keybd_event().
I've tried many things like throttling the rate of the events or trying
to repeat them multiple times if we didn't get anything but when running
the tests in a loop eventually we will be unlucky and the test will
The only reliable solution seems to be checking if the device has
received any data via GetDeviceData(), and if we don't see any events
there then we can win_skip(). AFAIU it will fail under Wine but just
skip on Windows.
The tests would still have sporadic skips and I am not sure if this is
any better than sporadic failures. Do we track those? This also creates
room for breaking tests on Window without noticing...
