This is the dmesg just after the problem arises. I have found out that disabling in Compiz - Opengl the following items: - framebuffer object - Vertex buffer object - Always use buffer swapping
Decreases the impact of the bug. At least the application windows are redrawn after artefacts show. It's however not completely gone. Unity bar is still heavily impacted. dconf reset -f /org/compiz && setsid unity makes (most of) the artefacts in the Unity bar disappear although not for long. ** Attachment added: "Dmesg just after artefacts show up" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1113454/+attachment/3522381/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1113454 Title: Artefacts with nouveau driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1113454/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
