Systems without xi2 don't use recent versions of wine and xi2 should be
avaliable now even for debian testing

That confirms what I've said in the comment #48: Wine due to its architecture
should implement this differently.

Is there a test case for that to confirm this behaviour?

That's unfeasible, especially for systems without xi2.

I agree with you totally.
I predict a specific response from Vitaliy ...

He said that it covers three Unreal Engine generations, and that's basically
what's being affected by this bug. Of course, if it doesn't work in windowed
mode, it is a hack, but it's still better than nothing.
If you believe that it's better to post all of the patches/hacks in a Wiki,
then you could create a page for it and give the link here, otherwise there's
not much use of patches scattered all over the Internet.
By the way, why is this bug still unassigned? It seems that the status should
be anything but "New" given that nearly 4 years have passed since the initial
bug report...

This won't happen - Wine uses hooks to deliver mouse and keyboard messages to
dinput. Hooks won't work without message loop. Not without complete rewrite at
least. And making it work another way means implementing fake drivers which
will be complete waste of time.
