[Bug 1510660] [NEW] Screen icons and text corrupted after 15.10 upgrade


You have been subscribed to a public bug:

Since upgrading to 15.10 I am having trouble with most of the desktop
and other icons and some text. 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.
