[ubuntu] Taking a screenshot generates an old screen

view story

http://ubuntuforums.org – This is the oddest thing I've ever seen. When I take a screenshot of a window or my desktop, I instead receive an older copy of the window or screenshot. What I mean, is that once I take a screenshot using gnome screenshot tool, I will forever get that screenshot when I try and take another. I'm running with the open drivers, under and amd/ati card. This happens using shutter, pressing 'printscreen', or using gnome screenshot tool. If I use the import command (from imagemagick) on the command line, I get the proper screenshot. I'll try and post a video so you can see what I mean. Has any (Hardware)
