You will NOT ENCOUNTER this bug if you check "Emulate Wine Desktop" in winecfg
That would suggest you don't have the correct modes setup in xorg if it crashes/doesn't work without the virtual desktop. Check the output of xrandr and compare it to the resolution that is set with the virtual desktop. (use xwininfo or something to get the window size if you can't guess it)
