slouken@6541
   770
           For the windowed resize problem; WMs each have their little quirks with
slouken@6541
   771
           that.  When you change the size hints, they get a ConfigureNotify event
slouken@6541
   772
           with the WM_NORMAL_SIZE_HINTS Atom.  They all save the hints then, but
slouken@6541
   773
           they don't all resize the window right away to enforce the new hints.
slouken@6541
   774
           Those who do properly do it are:
slouken@6541
   775
          
slouken@6541
   776
             - XFWM
slouken@6541
   777
             - metacity
slouken@6541
   778
             - KWin
slouken@6541
   779
slouken@6541
   780
           These are great.  Now, others are more problematic as you could observe
slouken@6541
   781
           first hand.  Compiz/Unity only falls into the code that does it on select
slouken@6541
   782
           actions, such as window move, raise, map, etc.
slouken@6541
   783
slouken@6541
   784
           WindowMaker is even more difficult and will _only_ do it on map.
slouken@6541
   785
slouken@6541
   786
           Awesome only does it on user-initiated moves as far as I can tell.
slouken@6541
   787
          
slouken@6541
   788
           Your raise workaround only fixes compiz/Unity.  With that all "modern"
slouken@6541
   789
           window managers are covered.  Trying to Hide/Show on windowed resize
slouken@6541
   790
           (UnMap/Map) fixes both Unity and WindowMaker, but introduces subtle
slouken@6541
   791
           problems with transitioning from Windowed to Fullscreen on Unity.  Since
slouken@6541
   792
           some window moves happen after the transitions to fullscreen, that forces
slouken@6541
   793
           SDL to fall from windowed to fullscreen repeatedly and it sometimes leaves
slouken@6541
   794
           itself in a state where the fullscreen window is slightly offset by what
slouken@6541
   795
           used to be the window decoration titlebar.
