[Desktop-packages] [Bug 1375007] Re: black window after minimizing
Morphis, 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 as it will automatically gather and attach updated debug information to this report: apport-collect -p xorg 1375007 Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information. As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful. Thank you for your understanding.
