           Summary: Diablo II: graphics go haywire after being covered by
                    another window
           Product: Wine
           Version: 0.9.42.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: owen.riddy(a)gmail.com


Diablo II can be started and run normally, as it has been for past versions of
wine. 
Up until version 9.42 it has been flawless, however since the upgrade to .42,
every time another application window covers the window Diablo is running in,
the game graphics vanish, to be replaced by a small Diablo head icon and some
small blue box (attaching image, and terminal output). Also occurs if game loses
focus.

I tried with the virtual desktop at 1024x768 & default settings, with no dll
overrides, and running the game at full screen (I got a proper error message
then: Error 25: A critical error has occurred while initializing Direct3D).

CPU usage spikes (50-100%) after the game window is returned to focus.

I'm running Ubuntu 7.04, Kernel 2.6.20-16, on a Dell Insperon 1300 laptop, if
that helps ^_^.

I'm not an expert, but I went through the terminal output, and it looks like the
issue is with:

fixme:ddraw:IDirectDrawImpl_SetCooperativeLevel (0x1e8ca0)->(0x10024,00000411)
fixme:x11drv:X11DRV_desktop_SetCurrentMode Cannot change screen BPP from 32 to 16
