<pre>Steps to reproduce:
1. run a gnome wayland session (as in Fedora 22)
2. open gnome system-monitor, display the process list. This only works if you
have enough processes so that a vertical scroll bar is displayed.
3. resize the columns in a way that they do not fit the whole screen width
4. hover the vertical scroll bar with your mouse
Expected behavior:
Scroll bar should fade in and out.
What happens:
While scroll bar is fading in and out it turns black for a short time. After
fading out sometimes the freed space is not redrawn at all but stays black
until content is refreshed.
I can reproduce this with at least one other gtk application:
nautilus (keep in mind that you have to repeat step 3. for this to work)</pre>
