Summary: Regression: WWIIOnline screen stops updating
                    (Regression tested)
           Product: Wine
           Version: 1.1.30
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d

        ReportedBy: [e-mail]

Under recent versions of Wine, WWIIOnline: Battleground Europe stops drawing to
the screen if the user clicks on the 'Settings' tab in-game.

Everything is still active in the background; you still hear the proper clicks
and noises from clicking on other GUI elements, and can exit the game by
guessing where the quit dialog is, but the visual display of the screen never
updates apart from the mouse cursor.

It starts with this commit:

wined3d: Don't reuse random GL contexts during initialization.

Obviously there's no guarantee about the state of such a context. The
specific
    problem is that it might have GL_UNPACK_CLIENT_STORAGE_APPLE enabled,
causing
    some glTexImage2D() calls to fail, but it's a bad idea in general.
