[Bug 371114] [NEW] massive artefacting in qt4 text areas (kate, skype, etc)

[naught101]

Public bug reported:

Binary package hint: libqt4-core

When I use Qt4 applications, I randomly get massive artifacting in text
areas. Artefacts appear either as parts of the desktop (including
widgets), or as random chunks of large (20-40px?), bold text, in an un-
related font.

This happens once every 5-20 minutes, and can be fixed by re-drawing
what's on each pixel (ie. by highlighting the area of text under the
artefact, or scrolling the affected areas out of view)

This mostly happens in Kate, but also in skype, and possibly other
programs. It's always in the text area (chat window in skype).

will attach files to show some examples.
