Bug ID: 39719
           Summary: Alex Hunter (hidden object game): custom mouse pointer
                    gets stuck (temporarily) when hitting the top of the
                    screen
           Product: Wine
           Version: 1.8-rc2

When custom mouse pointer is enabled in the hidden object game called Alex
Hunter: Lord of the Mind, the mouse pointer has some weird behaviour:
1. when you move the mouse pointer across the screen, it sometimes jumps to a
different direction then jumps back (this is the less annoying problem).
2. when the custom mouse pointer hits the top of the screen, the mouse becomes
unresponsive for 2-3 seconds.

Plain terminal output doesn't show anything suspicious. The problem exists in
fullscreen and virtual desktop mode as well. There's no such problem when
custom mouse pointer is disabled.
It can be reproduced with the demo version available from BigFishGames (you can
start the demo directly, without launching the BFG client, with 'wine
AlexHunterLordOfTheMind.exe').

When I made the comment in https://bugs.winehq.org/show_bug.cgi?id=32621#c7 , I
found that the problem was introduced by commit
841214ddb4d4dc620e6b51dfe6655b585d423edc.
