Test app triggering the problem
I wrote a small test app drawing an ellipse in its WM_CREATE message.
While this is properly drawn under Windows, the window stays empty in ReactOS.
I've attached my test app illustrating the problem.
You can compile it with: gcc -DUNICODE -o wndtest.exe main.c -lgdi32
