--- Comment #9 from Mike Ruprecht cmaiku@gmail.com 2008-12-10 20:35:30 --- Created an attachment (id=17817) --> (http://bugs.winehq.org/attachment.cgi?id=17817) Example of the cursor corruption.
The top half of the cursor is an inverted image of this buffer from the same x position as the cursor, but the y position is the section from half the height to the whole height of the cursor (see attachment).
