M, this bug was reported a while ago and there hasn't been any activity
in it recently. We were wondering if this is still an issue? If so,
could you please run the following command in the development release
from a Terminal as it will automatically gather and attach updated debug
information to this report:

apport-collect -p xorg 1354841

Please ensure you have xdiagnose installed, and that you click the Yes
button for attaching additional debugging information.

Thank you for your understanding.

Title:
  Screen corruption (characters are drawn as black squares)

Status in “xorg” package in Ubuntu:
  Incomplete

Bug description:
  Sometimes, the characters are rendered as black squares (cf attachment). I couldn't find any event in the systems logs that could explain that.
  I can "stop" the bug by changing the anti-aliasing options in the system settings (enabled / disabled, level of hinting) and restarting the applications, but the squares can come back later on, and I have to repeat the operation.

  The bug almost exclusively happens with firefox and thunderbird,
  though krunner is also affected (but not other kde apps). I'm not
  using many GTK applications, but I can also see the bug with unison.

  It used to happen in 13.10 as well, and upgrading to 14.04.1 hasn't
  improved the situation
