Thanks for the patches, I'll take a look at them. Though I think 
WS_EX_TOPMOST deserves special handling, because it can't be modified 
with SetWindowLong like other styles.

BTW, I can't find where WINED3DCREATE_NOWINDOWCHANGES is set at all. 
It's checked in a couple of places but not set anywhere in whole wine 
tree. Is it even used anymore?
