Actually I was saying that DGA mouse freezes the mouse pointer but it can still
be forcefully warped by wine, to mimic normal movement and interact with other
applications - but it disables mouse acceleration in doing so, so such behavior
is only acceptable when the active window has cooperative dinput active, in all
other situations the DGA mouse grab must be released and normal mouse movement
used.

To the user the only difference between having a cooperative dinput window
active and having a normal window active, is that mouse acceleration changes,
and there might be a very slight lag (1 refresh).

All normal application interaction would be preserved.

I did say that DGA support is necessary, I only brought up the "hidden mouse"
fallback (where warping is required and the pointer MUST be hidden) as a
possible fallback that has many undesirable side effects, I recommended against
using such a method if at all possible, because it is not robust at all.

It was only in a summary of possible solutions, and noted as having many
problems.

Where as DGA + mouse warping to mimic real movement would be at least somewhat
robust.

You are clearly not understanding what I am talking about then.

This cooperative mode using DGA would ALTER the mouse movement behavior
(because wine is really doing the movement), but not disable it, it would still
be able to interact with all normal applications even while the cooperative app
is focused - but as soon as the app is defocused it would return to normal
movement to restore expected behavior (mouse acceleration).

I look forward to seeing an XInput2 solution.

However users will continue this discussion until everyone is running xorg 7.5
- and I do not expect that to happen for years, there are still people running
debian stable and expecting wine to work.
