I have made updates today and yesterday according to the attachment. My computer with Radeon HD 6670 has the same behaviour as mentioned by WeeGee. The update of unity-system-compositor makes it a little better. In case I place the cursor in the input field in the login screen, there are no corruptions, but as soon as I type anything or move the cursor, the graphic corruptions starts.
