There are two groups of changes that I can see here. One is the huge IME 
change and the other is the smaller change to use the 
_decodeWM_ENTERSIZEMOVEParams::: and -decodeWM_EXITSIZEMOVEParams::: 
methods. I would expect that the problem comes from the later. Could you 
please try to restore the windowEventProc method to its SVN state and 
just comment out the call to resizeBackingStoreFor in 
decodeWM_EXITSIZEMOVEParams (You'll find that in the file 
win32_movesize.m)and report back the results.
