Hmm, this entire problem is pretty tricky, and it goes beyond ddraw. We have 
to attack the broader set of problems.

For starts, we need a few tests to find out

*) Does ddraw change the window params at all, and if yes, when(your test 
already answers part of that).
*) How does restoredisplaymode behave
*) Does ddraw restore the display mode on SetCooperativeLevel(DDSCL_NORMAL)
*) Does ddraw restore the display mode on ddraw device release? On primary 
surface release?
*) Who restores the display mode on app exit if the ddraw iface is not 
released? What happens with the window in that case?
*) Who restores the display mode on an app crash?
*) How does User32.ChangeDisplaySettingsEx FULLSCREEN flag(= temporary mode 
change) work?
*) What happens if two different apps set conflicting FULLSCREEN modes?
*) How does the CDS FULLSCREEN flag affect the window?

And I am sure more questions will arise during the testing process
