Default libreoffice with ubuntu 11.10 and 12.04 - most of the menus under libreoffice are half visible or not visible ( a "_" is visible in place of most menus and options under it). LibreOffice 3.5 and 3.6.0.1 Ubuntu 11.10, 12.04 http://ask.libreoffice.org/question/1429/libreoffice-3512-menu-problem/

Set this bug to Bjoern. He is the maintainer for LibreOffice in Ubuntu. Maybe he knows the problem.
While I have never experienced this problem with LibreOffice under Ubuntu, I have an idea. You seem to be using Arial, a MS proprietary font, as your UI font. I have observed that these fonts disappear from the UI if I don't give proper permissions to the font files. You may want to check file permissions with your file manager.
Also seeing this in ThinLinc (a VNC server) in multiple versions: - SLED 11: 3.6.5.2.15 - Fedora 18: 3.6.6.2 - Fedora 19: 4.0.3.3 So it seems to be a general bug rather than something distribution specific. Looking at the behaviour, it looks a bit like there is a race going on between the code filling out the menu, and the code blitting it to the X server. Opening the menu will randomly get some of the entries. Compositing (e.g. gnome 3) also solves the problem.
Also happens with Fedora's bundled TigerVNC server.
Turned out to be a VNC issue in our/TigerVNC's case. The "Glyphs" XRENDER operation is no longer built on top of the "Composite" operation, so change tracking was off. Fixed upstream. Sorry for the noise.
