  I've seen this problem in this PC for years. Many times Linux works
  normally, without problems. Every now and then, depending on the
  programs I open, Ubuntu (and other Linuxes I tested) switches into a
  "graphic corruption mode": some screen elements are not drawn correctly.
  
  For instance, while navigating with Firefox, after scrolling down on a
  webpage, only the lower part of the screen scrolls down, the rest
  remains as it is. If you hover the mouse cursor over links or tries to
  select text, then appears in the screen some text that was not shown
  without selecting. In other words, the webpage scrolls down, but the
  display is not updated correctly unless you select text. Unfortunately,
  I could not take a screenshot of Firefox with problems because the
  screen is updated and no more error is shown, neither in screen nor in
  screenshot.
  
  The worst problem seems to be Emacs, screenshot attached. The white
  background is not shown, in its place is shown whatever was shown before
  selecting the Emacs window, like the desktop or other window's contents.
  Most of the times the "graphic corruption mode" is switched on is
  because I started Emacs, but not only Emacs causes this. On other
  distributions I got that problem very often using yakuake (IIRC it was
  Gentoo).
  
  If I switch to terminal (Ctrl + Alt + F1) and change back to desktop,
  the "graphic corruption mode" is switched off, and screen mostly show
  the correct elements, except for some black or white lines that are
  shown occasionally.
  
  To make the situation even worse, sometimes, instead of entering
  "graphic corruption mode", the computer freezes. Only the mouse cursor
  still moves, nothing else. The programs continue running after the
  freeze (I can tell you that for sure) but without input and output all
  that is left for me to do in that situation is a hard reset.
