The tests pass on Windows XP, and of course Wine.

Since I heard nothing on this, I make a request here

Sorry, I haven't noticed the patch earlier. Please nadd the component the patch addresses in topic, for example "ddraw: Resize fullscreen win..." - that makes them more visible for me when I look for ddraw/d3d related patches.
As for the patch itself WineD3D.dll already has similar window resize code. Do you know why it doesn't resize the window, and if we can make wined3d do this job?

There is IWineD3DDeviceImpl_SetupFullscreenWindow, but that one is not
exported so it can't be called from ddraw as it is.
Calling it from within IWineD3DDevice_SetDisplayMode seems troublesome since the hwnd to use is not always available in the WineD3DDevice. See for instance this example from CreateSwapChain:
/* Setup hwnd we are using, plus which display this equates to */ object->win_handle = pPresentationParameters->hDeviceWindow; if (!object->win_handle) { object->win_handle = This->createParms.hFocusWindow; } if(!pPresentationParameters->Windowed && object->win_handle) { IWineD3DDeviceImpl_SetupFullscreenWindow(iface, object->win_handle,
pPresentationParameters->BackBufferWidth,
pPresentationParameters->BackBufferHeight);

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

Ah, I forgot to add yesterday, that writing some tests about mode changes is on my todo list, although not within the next few weeks.

What's the current status here? I've been up to the nose in other things,
but I should be able to check a few things out if needed.
