Q1.
There's this image (from my last Google Chrome session) that's appearing in my Dash. There's one different image appearing in shortcut overlay (on "press-hold" Super button). This is un-intentional, so first I'd like to know a way to remove it. Logging out and back in works, but that doesn't seem to solve it permanently - the problem reproduces.
Here's a snapshot: (ghost of facebook page) (Please note the ghost of a facebook page within the Dash overlay area. The only window in the background is of Firefox with a blank page.)
..here's Gnost Of Nautilus,
..and this is the Ghost Of System Monitor
Q2.
Dash's been behaving weird lately with videos or animations playing in the background. The video/animated-image flash through the Dash. (The problem persists through sessions.)
These two snaps below should explain the problem visually:
<1> (Note the youtube video is being displayed through the Dash.)
<2> (And here's the same with a video being played with VLC.)
How to fix that? Or is this normal, or a bug?
