[Wine] [Wine 1.4rc1]Mouse support broken in MassEffect and Bioshock

[nepenthes]

Hi,
I upgraded to wine 1.4rc1 from the official wine PPA for ubuntu Oneiric Ocelot (11.10), I am running Ubuntu 12.04 alpha, and mouse support seems broken for Mass Effect (the first one) and Bioshock (the first one too).

I have made some tests with a clean wine prefix.

The works smoothly in the game menus, but after a level is loaded, it seems the mouse x an y axis are not recognized anymore : if i move the mouse to the left or rigt, the view always go the right (iirc), so i have to turn 360 degrees to get back to the same view. 
The other axis is really slow, and gets stuck to the highest or lowest border of the screen as soon as i move the left/right axis.

The mouse works fine in Worms Armageddon and Source games (Half Life 2, ep1 and 2, left 4 dead 2).

Can anyone confirm this report ?
Is it fixed in 1.4rc2 (i have seen something about clipping in the git commits) ?
