I had same problems with Nautilus. Something to do with MS ttf fonts. The solution for me was to open terminal and type:
fc-cache -rv Then log out and log back in. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1506704 Title: Thin font, nautilus doesn't integrate with Unity. Status in gnome-settings-daemon package in Ubuntu: Confirmed Bug description: It happens frequently (around 1/2 of the time) that when I boot the computer, font lines are only one pixel thick. This concerns watch in the sys-tray, all item in the menu of all applications, as well as all fonts in Nautilus. When this happens. Nautilus doesn't display menu in the Unity menu bar, but displays an additional button showing three horizontal lines for bringing up the menu. This problem has been with me for years, although sometimes disappears for months at a time when I run sudo apt-get update. This time it re- emerged after upgrading to 15.10 beta (Wily). It happens usually on power-up, and disappears after system restart. (To appear again on the next power-up).
