Setting a bookmark pops up a small notification button near the bottom right of the screen -- "Mark set: a"

That notification button never disappears, and when I scroll the screen it leaves a trail of copies smeared across the screen.

Just noticed this:

on my regular x-windows system, the button and the smeared copies do eventually fade and disappear;

on my remote x-windows system, the button and the smeared copies never disappear.


Reproducible: Always

Steps to Reproduce:
1. Open a file longer than a single screen
2. Create a bookmark (ctrl-b)
3. Scroll the window


Actual Results:  
"Mark set:" notifier appears
When the window is scrolled, the button smears multiple copies up/down the screen

Expected Results:  
"Mark set" notifier disappears quickly and does not spam the screen,


Ideally for me, the "Mark set" notifier could be disabled completely.

There is already a color change to the line that is being bookmarked which is plenty of notification that the bookmark has been made.
