Thank you Austin for confirming the bug. There seem to be a huge (32759x32759 32 bpp) bitmap / pixmap / image involved (someone that knows X11 might help me out with the terminology?). The immediate cause of the crash would seem to be a X error (and the real issue that Wine does not work around the limitation...), do anyone know a possible workaround, maybe involving the Xorg config? (Info on how to work with Xorg.conf (without totally destroying the auto-detection) in a recent X.org would be nice as well, but that is almoust certainly OT) For those not following the bug as well: A WINEDBUG=+x11drv log: http://bugs.winehq.org/attachment.cgi?id=17915 Just wondering: Is this by any chance the kind of issue that might be addressed by the DIB engine? (I had a look at my Wine-git source code, found it interesting and decided that my mostly embedded C / Windows C++ knowledge Is probably not really relevant for Wine's X11 code... All I managed to figure out is that this is probably where the error comes from: http://tronche.com/gui/x/xlib/pixmap-and-cursor/XCreatePixmap.html ) Gert
