** Description changed:

  THE ISSUE:
  The pointer (happens with mouse, but it's worse with touchpad) fails to click 
or highlight any object at the very last pixel of the left and top borders of 
the screen. If there is a menu at the top, for instance, the highlighting that 
should appear on top of it starts to flicker on and off. If the icon 
highlights, I can click. If it doesn't, clicking such menu icon doesn't have 
any effect. It happens at the last pixel of the screen. Moving the pointer just 
one pixel away from the border restores the desired effect.
  
  This affects any desktop environment made with gtk+3, such as MATE,
- Pantheon, parts of Xfce, Budgie and probably others. GNOME is not
- affected. Any DE still using gtk2 works fine. I tested 3 different
+ Pantheon, parts of Xfce, Budgie and probably others. GNOME and Unity are
+ not affected. Any DE still using gtk2 works fine. I tested 3 different
  computers with Intel Graphics and they were all displaying the same
  glitch.
  
  It can always be reproduced. I can record a video of the issue if
  needed.
