D14850: [effects] Turn off Translucency by default

luebking added a comment.


  The functional justification for translucent moving/resizing windows has always been to control its geometry in relation to windows lower in the stack ("what and how much will be covered", "where's a free area")
  There may also have been references to early WMs when windows were just hinted by an outline during geometry transitions (though typically not unmapping the actual window), simply because displaying them while resizing them is resource intense (what's more of a concern when you're short on resources) - those WMs would often have presented an outline to allow controlling the initial position for the window before actually mapping it.
  
  Turning inactive windows translucent was some cheap global dimming (w/ false positives in case of eg. video players) to stress the active window.
