There is a test for that somewhere in dlls/d3d9/tests/device.c (or some other 
test file in there).

But IWineD3DSurfaceImpl_Release will destroy the gl texture of a surface when 
the surface is destroyed.

Also, if the gl surface still knows the texture, the following could cause an 

SetCursorProperties(cursorSurface, ...);

<render some stuff>

LockRect(cursorSurface, ...);
<write some thing into the surface>

The PreLoad will then change the cursor without SetCursorProperties beeing 
called. This should not happen. I tested that with some hacky test. 
Unfortunately this cannot be automated in the visual tests because cursors do 
not show up in screenshots.

This is my hacky cursor test app:

The successor of that file without the cursor tests is now in 
dlls/d3d9/tests/visual.c. I think this visual.c version is not the version I 
used for checking later surface changes.
