So, I was trying to drag and drop an image, but for reason I am now stuck with two mouse cursors for some reason (not to mention the image itself is hanging around). image to explain (photo cause the cursor doesn't appear in screenshots) :
As you can see, there's two cursors – they're also flattened out weirdly, and the image that was being dragged is still there. I have no idea what happened. I'm using Ubuntu 14.10.
