I am not familar with the rhythembox codebase, but it seems to be an error in styles.css that causes the white line.
As a workaround you can directly apply the patch attached to the styles.css in your system which can be found in /usr/share/rhytembox. When rhytembox is started next time the white line should be gone. If some package maintainer reads this, feel free to adapt the patch, but I have only done very limited testing. ** Patch added: "style.css patch to remove the 1px border of the primary toolbar" https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/1448272/+attachment/4417302/+files/rhytmbox_white_line.patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to rhythmbox in Ubuntu. https://bugs.launchpad.net/bugs/1448272 Title: White line between the interface and the application window title Status in rhythmbox package in Ubuntu: Confirmed Bug description: lsb_release -rd Description: Ubuntu 15.04 Release: 15.04 Software version rhythmbox 3.1-1ubuntu3 What i expected to happen I think that space between header and application interface should not exist Additional information: I just installed OS.
