In case the game is writing past the memory block of the locked texture, it
might expect the mipmap levels to directly follow the memory block of the
texture. It is not officially supported, but there are also other games which
rely on this. They try to be very efficient (or buggy) by writing over the end
of the returned memory to directly update the mipmap levels. Wine does not yet
support this, see bug 34480 for more information. You could add a hack to
allocate twice the amount of system memory for a texture. One example for such
a hack can be found at (just remove the checks for the resource size, the patch
targets a specific game):
