When accessing user added sub menu applications (button to the right of main launcher showing downwards expand arrow) the active lit state of the button remains lit if closing the sub-menu launcher by clicking on the desktop. Sweeping across the panel launchers with the mouse pointer will reset them back to normal state. Closing the buttons manually when entering and leaving the applications sub menu works correctly as expected. This odd behaviour has been present since the move to GTK3. Still present in version 4.14.
The first point release will include a fix for this glitch (bug 15818). *** This bug has been marked as a duplicate of bug 15818 ***
