Hello and thank you for this bug report. This is strange but it's maybe due to your video card and its drivers...
Can you try to use the dock without the OpenGL backend? (cairo-dock -c) Which drivers do you use? Can you post the output of this command: glxinfo |grep OpenGL (mesa-utils package is needed) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/809708 Title: Certain cairo-dock updates correlate to X freezes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cairo-dock/+bug/809708/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
