            Bug ID: 42726
           Summary: Windows areempty and very small: null_driver instead
                    of X11
           Product: Wine
           Version: 2.4
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: winex11.drv
          Assignee: wine-bugs at winehq.org

screenshot: totalCmd. winecfg behaves the same way

Building Wine from source.

target: National Instruments RT Linux, 64bit
4.1.15-rt17-4.0.0f0

config:
 --disable-tests --with-x --without-xrender --without-freetype --enable-win64

Result:
X-windows apps show empty and/or very small windows.
They react to keyboard but there isn't anything rendered inside the windows.

Text applications (e.g. wine64 cmd.exe) run OK.

I tried to add debug prints into the code.
Found out that gdi32/driver.c detects the X11 and looks up the X11
gdi_dc_funcs*
but gdi32/bitblt.c/StretchBlt calls nulldrv_StretchBlt ignoring that there is
X11 already detected.

Same behavior when emulating a virtual desktop (copied ~/.wine/*.reg from a
working install because even winecfg doesn't render).
