title: Eclipse slow typing
body: <p>I have eclipse running under awesome-wm. 
  The program itself runs fine but keyboard input has a lag ~300ms which is really annoying.  Also scrolling with mouse is ok, but scrolling with PGup or PGdown or arrow keys is laggy, and when entering text the cursor blinks weirdly.</p>
  
  <p>However, when I changed to window-maker or xfce wm everything works ok.</p>
