Bug ID: 53334
           Summary: X11DRV_SelectionRequest conflicts with OpenClipboard
           Product: Wine
           Version: 7.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When an X11 application requests clipboard data from Wine,
X11DRV_SelectionRequest() calls OpenClipboard() to access the process
clipboard.  During this period, any attempt from the Windows application to
access the process clipboard will fail with error ERROR_ACCESS_DENIED.

This especially causes problems with some IMEs (e.g. fcitx5) that have
clipboard history feature built-in; it is unpredictable when it will request
clipboard data from Wine.
