            Bug ID: 48772
           Summary: Attack on Titan 2 continually clips the cursor,
                    resulting in incorrect cursor events
           Product: Wine
           Version: 5.4
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
          Assignee: wine-bugs at winehq.org
          Reporter: qsniyg at mail.com
      Distribution: ---

For example:

...
0009:trace:cursor:SetCursor 0x20046
0009:trace:cursor:ClipCursor Clipping to (-3,-12)-(1923,1093)
0009:trace:cursor:ungrab_clipping_window no longer clipping
0009:trace:cursor:ClipCursor Clipping to (-3,-12)-(1923,1093)
0009:trace:cursor:ungrab_clipping_window no longer clipping
0009:trace:cursor:ClipCursor Clipping to (-3,-12)-(1923,1093)
0009:trace:cursor:ungrab_clipping_window no longer clipping
...
0009:trace:cursor:SetCursor 0x20046
0009:trace:cursor:X11DRV_MotionNotify hwnd 0x10052/4400003 pos 963,543 is_hint
0 serial 6080
0009:trace:cursor:ClipCursor Clipping to (-3,-12)-(1923,1093)
0009:trace:cursor:ungrab_clipping_window no longer clipping
0009:trace:cursor:X11DRV_MotionNotify hwnd 0x10052/4400003 pos 924,521 is_hint
0 serial 6083
00ce:trace:cursor:X11DRV_SetCursorPos warped to 960,540 serial 6413
001f:trace:cursor:X11DRV_EnterNotify hwnd 0x10020/3a0000a pos 921,509 detail 2
0009:trace:cursor:ClipCursor Clipping to (-3,-12)-(1923,1093)
0009:trace:cursor:ungrab_clipping_window no longer clipping
0009:trace:cursor:ClipCursor Clipping to (-3,-12)-(1923,1093)
0009:trace:cursor:ungrab_clipping_window no longer clipping
...

Since the cursor is continually warped to the center of the screen, when
ungrab_clipping_window calls XUnmapWindow, it reports to the game that the
cursor has moved back to the center, resulting in the common "camera refuses to
move" bug.

Although the documentation[1] states that XUnmapWindow does nothing if called
on a window that's already unmapped, when adding a variable to keep track of
whether it's mapped or not and only unmapping it when needed, the issue is
fixed.
