   Oooo, I just took this code out of my configs and boy do I hate that   
   borderless display!!!   
      
   This is how I fixed it.  It works for me.   If you read the code as much as   
   you may or may   
   not be able to there are 2 variables used by a gtk theme that have to be in   
   that theme you   
   are using.  95% of the time it is there.  My fix uses those color variables to   
   change your   
   display.   
      
   This is in a file called ~/.config/gtk-3.0/gtk.css   
   Add these lines to that file if it exists, or create it and add them.   
      
   Any theme you use, has it's own gtk-3.0/gtk.css file, and in there, are   
   defined colors for   
   that theme. like:   
   @define-color theme_selected_bg_color #f85600;   /* dark orange */   
   @define-color theme_selected_fg_color: #FFFFFF;   
      
   If you can't find them, and the borders look horrible still, then add them and   
   make them   
   colors that go with your theme.   
      
   This all was done with metacity themes but I think that was dropped in/after   
   Mint 19.   
   Good luck.   No harm done if this does not work for you, just reverse what you   
   edited.
