Advice fixing #13683 (DirectX mouse overlay?)

Using WINEDEBUG=+all, the resource in question (static/bitmap16.flx) is 
loaded via kernel32's CreateFile, ReadFile.

Is there a way to trace only kernel32 calls dealing with a specific file 
handle? I'm curious if there are any failed reads. Does that seem like a 
reasonable next step?
