The patch was designed to avoid false positives from messages such as 
WM_DWMNCRENDERINGCHANGED where lparam is 0:

https://testbot.winehq.org/JobDetails.pl?Key=67055#k108
dxgi.c:5063: Test failed: Got unexpected message 0x31f, hwnd 001C01E4, wparam 0x1, lparam 0.

But of course it won't help with unexpected WM_WINDOWPOSCHANGING, 
WM_GETMINMAXINFO and WM_WININICHANGE messages since lparam is a pointer 
for those (lparam is sometimes NULL for WM_WININICHANGE). Fortunately 
these are pretty rare, they happened only three times in the recorded 
history (vs. 153 instances of WM_DWMNCRENDERINGCHANGED):
