You are as quick as usual ;)

The output of the log is not as informative as I had hoped. Perhaps you can add
some printf-like lines to get some more info. Don't worry I will give hints on
where to place them.

The surface conversion code is in dlls/wined3d/surface.c around line 4562 (you
will see 'if(desc.convert) {'. The end of this block calls
'desc.convert(This->resource.allocatedMemory, mem, pitch, width, height);'. Try
to print the values of pitch, outpitch, width and height. Also print the two
pointers (allocMemory and mem).

The 'broken' function at some point is 'static void convert_r16g16(const BYTE
*src, BYTE *dst, UINT pitch, UINT width, UINT height)' in utils.c (this is the
function pointer desc.convert is set to). Play a bit with the function. Perhaps
make sure it won't get called (or return at its start).
