--- Comment #10 from Christian Costa titan.costa@gmail.com 2012-10-09 14:26:30 CDT --- The window area size is 1280x1043 instead of 1280x1024. There are extra 19 lines which should correspond to the menu height. Did you see a menu bar or any decoration when the window was not in fullscreen?
It seems the wine x11 driver does not like this window area size bigger than the screen. It can be a xorg but this can also come from the wine x11 driver. It seems Alexandre are doing some work in that area. Maybe it's related to this changes. Just wait my patch is committed and rebase to latest git and then file a bug if the crash persists.
