Bug ID: 43680
           Summary: Epic Games Launcher crashes if tool-tip is shown in
                    D3D11 mode
           Product: Wine
           Version: 2.16
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3dx11
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Tested with Wine staging 2.16.

How to reproduce:
- run EpicGamesLauncher.exe (maybe you need the "-SkipBuildPatchPrereq"
parameter)
- wait until the login window is shown
- everything seems to be ok
- move the mouse over one of the fields where you can enter email/password
- the window starts to flicker and finally EpicGamesLauncher.exe crashes

If you launch EpicGamesLauncher.exe with "-OpenGL", you do not get the crash.
Therefore I assume that it is a problem with D3D11.
