gnome-screenshot takes the wrong screenshot when using "select area to grab" if the content changes

[Dima Ryazanov]

When using "Select area to grab", I expect to get a screenshot of exactly the content that I selected. However, if that area changes right after I'm done selecting it, gnome-screenshot saves the new content, rather than the content I saw while I was selecting it.

Example: taking a screenshot of a popup that appears on mouse-over. I can see it correctly while selecting the area, but the popup disappears before the screenshot is taken.
