Summary: Steam tray menu wrong highlight
           Product: Wine
           Version: 0.9.47.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

In Wine 0.9.47, the tray icon menu in Steam is higliting entries incorrectly.
When I hover over an entry (e.g. Friends, Community, Servers), that entry is
highlighted but immediately after that the entry above it is highlighted and it
stays that way. Only moving the mouse for a pixel makes the highlight jump from
the entry above to the right one and back immediately. If I click on an entry
while the mouse is still it opens the wrong one also.
