That's a very odd error. I'm using various versions of Ubuntu
(including 12.04) and don't have that problem. My best guess is that
it's some issue between your graphics card/driver and the display
manager.
A quick thing to try. If you grab and drag the block from the block
tree to the canvas and then hold it there for a couple of seconds,
does anything change? What if you drag and drop very quickly? (I have
some recollection of seeing an issue like this at some point).
