Bug ID: 43474
           Summary: Tsukihime fails fullscreen -> windowed transition
           Product: Wine
           Version: 2.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

Switching from fullscreen to windowed mode causes empty window or unmapped
window that needs to be restored with xdotool windowmap. Tsukihime can be
started in windowed mode but switching to fullscreen and back breaks it
(fullscreen always works). Log with fullscreen -> windowed in main menu (after
2 splash screens) is attached, maybe this piece is the culprit?.
