Yes; the hardware didn't suffer from the problem before 10.04 or with the live CD. So it is the driver *installed* in 10.04 that causes the problem. However, it is linked to using a Matrox card.
I've not seen bug https://bugs.launchpad.net/bugs/439448 with the Matrox card, but have seen it on other machines with Intel graphics, so I'm not sure that is a related bug, although it seems to affect the same end (right hand side) of the top panel so maybe there is a link.
