Bug #: 31911
           Summary: Dota 2 freezes randomly during game
           Product: Wine
           Version: 1.5.14
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

When playing a match or even sometimes at the main menu, Dota 2 will freeze up
and I have to switch to another desktop and kill the process.  When looking at
the log from Steam, I see a bunch of this:

err:d3d_surface:surface_blt_fbo >>>>>>>>>>>>>>>>>
GL_INVALID_FRAMEBUFFER_OPERATION (0x506) from glBlitFramebuffer() @
/var/tmp/portage/app-emulation/wine-9999/work/wine-9999/dlls/wined3d/surface.c
/ 1265

Followed by:

err:ntdll:RtlpWaitForCriticalSection section 0xd68d5c4
"/var/tmp/portage/app-emulation/wine-9999/work/wine-9999/dlls/winex11.drv/bitblt.c:
surface" wait timed out in thread 0009, blocked by 002b, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x7ed4e8e0
"/var/tmp/portage/app-emulation/wine-9999/work/wine-9999/dlls/user32/user_main.c:
user_section" wait timed out in thread 0037, blocked by 0009, retrying (60 sec)

I am using the latest version of wine from git.

I have attached a full log.
