           Summary: Application window fails to be rendered after
                    resize/minimize/restore cycle in managed mode
           Product: Wine
           Version: CVS/GIT
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: regression
          Severity: major
          Priority: P2
         Component: winex11.drv
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: a_villacis at palosanto.com


Somewhere between 0.9.56 and 0.9.57, a regression was introduced that causes an
application window (in any app) to fail to be rendered properly. To reproduce
(with Wine Notepad, but any application can be used):

1) Run: wine notepad
2) Drag app window border to make it bigger. This (apparently) works.
3) Minimize application window using the WM decorations (tested under
GNOME/Metacity).
4) Immediately after minimize, try to restore the app window. Almost all of the
tries result in the window failing to be restored properly. Only a tiny
rectangle appears in the upper left corner. 

I found this bug after doing that very same sequence as described above. I have
tried to bisect this, but I didn't have time to complete it. I have narrowed it
to:

This bug is confirmed at my home computer and my work computer. Both are
running Fedora Core 8.
