Sounds like that the surface conversion code still makes some assumptions about the allocated memory size and the surface size. Wine used to allocate the full power of 2 size, but I removed that and allocate only the real surface size because there are some applications which expected a specific pitch for the surface. The power of 2 size usage vs real size was pretty inconsistent, I guess there is another inconsistency.
