RD, the next step is to fully commit bisect from kernel 4.2 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your help. ** Tags added: kernel-bug-exists-upstream kernel-bug-exists- upstream-4.7-rc6 needs-bisect regression-release -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1599952 Title: Blurred images with kernels after 4.2.x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1599952/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
