That's the consequence and not the real place where the problem is.

Wine'd dinput warps mouse in some cases (much lesser number then it was
before) while it shouldn't do that at all!

The real issue is in x11drv which should warp mouse and report
"relative" mouse moves while it doesn't. I've sent two patches that
haven't been applied yet.

See bug 6971 for more info.
