I can confirm something similar happening to me. Sometimes, after startup icons are fine for something like 20 seconds and after that they turn into non-decorated ones using some horrible theme. Nautilus is the only application suffering from this as you can see from screenshot attached - unity panel is not affected.
Strange is that this does not happen everytime but simply randomly. I have similar log records as listed in #7 and using post-release Nvidia driver. Will try downgrading to nvidia non-post-release version. ** Attachment added: "screenshot" https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/873545/+attachment/2564844/+files/screenshot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/873545 Title: After update Nautilus icons are black/white, no decorations of breadcrumb etc. To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/873545/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
