OK.  Can you try the same I asked Evgeni?  In xdisp.c remove this code

   if (window_resize_pixelwise)
     {
       width = height = 1;
       goto virtual_glyph;
     }

and check whether setting `window-resize-pixelwise' to t still changes
the behavior.  The expected answer is "no".

Thanks, martin
