John Deakin, if you boot into a kernel from the prior release, is this still reproducible?

The problem seems to be that the screen painting lines are out of synch. This means that most of the icons on the desktop are almost unreadable and spread laterally. Also PDF documents are unreadable. The raster graphics that I have imported into Inkscape are unusable. I am using a Dell Vostro 220 and Dell screens. The affect is the same whether I use a wide screen or a more conventional profile.
