When using the gnome-screenshot to capture screen, an irrelevant area of the 
screen is captured. It could be the login background or 'cached' screen area 
from windows that have been opened and closed a long time ago, instead of the 
real area captured with the cursor selector.

This will might not be a gnome-screenshot at all, and more probably an
intel hd graphics driver issue, since using any alternative packages for
screenshoting or screencasting will end in same result.

Another strange thing is that on cold boots, everything is working
properly for a while, but after some time, and after screen locks, the
capturing tools will again start to misbehave.

Here are some screencasts captured with kazam, exposing a similar issue:
