yes, you have to alter Wine source and build it yourself... Alternately... you can work around the bug. Move the mouse to the side of the screen right away when launching.. the window should come up. barely move the mouse on the edge (over no actual parts of the window that will interact with the cursor) and click on the window somewhere, then move the mouse back to the edge of the screen. Then use the keyboard... keys, Tab and Enter to get everything done and log in.
