They have a solution for this, but I think you will not like that
solution. See for example the comment at method -initWithDevice: in
Win32CairoSurface.m:

// FIXME:
// Non-retained backing store type on windows doesn't re-display
correctly
// after first time (see additional comments in method -[CairoContext
flushGraphics])
// Currently handling such windows as buffered store types until a fix
can be resolved.

And the comment in -flushGraphics:

  // FIXME: Why is this here? When is it called?
  // Comments added 07/20/2013 to address the above question after
  // further debugging cairo/MSwindows non-retained backing store type:
  // This is called from NSWindow/flushWindow for the non-retained
backing
  // store case.  This code originally seems to have been added due to
the 
  // non-retained backing store type NOT showing up on XWindows/Cairo
combination
  // and added this XFlush call to handle this case.
  
  // For MSWindows a similar problem seems to occur. However, the only
  // equivalent to XFlush on MSWindows is GdiFlush, which doesn't cause
  // the window to re-display properly.  So, on MSWindows, the
non-retained
  // cairo backend surface is currently excluded from the build and we
  // handle it as a buffered window expose event for now.
  // FIXME:  Anyone know how this can be handled/fixed correctly...

Unfortunately that branch currently doesn't compile and is the version
0.23.1. After some changes I'm able to compile it, but the apps crash
after start. I suppose is incompatible with current gui.

So I will make a patch for people who wants use GNUstep on Windows. I
will use my changes because there are small compared with the solution
in TestPlant branch.
