--- Comment #6 from Julian Lubenov julianlubenov@abv.bg 2008-06-18 00:13:21 --- Created an attachment (id=14146) --> (http://bugs.winehq.org/attachment.cgi?id=14146) if you make the window smaller
if you resize the window and make it smaller the part that have to be copied from the back buffer is smaller and the black area is bigger. And because it incorrectly copied the bottom left part of the back buffer the result is this big black area at the screen and the graphics pushed much upper than before.
