[Bug 1035901] Re: graphical corruption appears in unity on macbook ( horizontal stripes at the top of the screen)

 

Tommy_CZ, 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 test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p xorg REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is
already available, doing this on a release prior to the development one
would not be helpful.

Thank you for your understanding.

Title:
  graphical corruption appears in unity on macbook ( horizontal stripes
  at the top of the screen)

Status in “xorg” package in Ubuntu:
  Incomplete

Bug description:
  Hi, I installed Ubuntu and found I have graphical corruption at the top of the screen, few horizontal stripes. If some window lose focus, it can be covered by them. Window with focus DOES cover it. Another user doesn't see it (the bug doesn't occur).
  It came after I upgraded intel GPU drivers via ubuntu X-SWAT, so I uninstalled them using ppa-purge, but it didn't help.
