Actually, it looks like the bug wasn't completely fixed in Wine 1.3.36. Whether
a partly off-screen window is refreshed properly seems to depend on what
proportion of the window is off-screen.

Testing with WinUAE, with Wine 1.3.36 the window refreshes correctly when a
small proportion of its area is off-screen. But in a different position with
the window mostly off-screen, the window is not refreshed.

Nevertheless, things have regressed with Wine 1.4rc1, since the window never
refreshes even when only a small part is off-screen. So I noted the
partly-working case as "git bisect good" in the regression test.

The regression test reported this:

    ddraw: Use the window's client rect for clipping.
