I'm not sure about the relation. It would be better to have screenshots to compare.
Assuming that the bug could be related to language, I uninstalled Brazilian Portuguese, left everything in English and restarted Ubuntu. The procedure for test is double click files DOC, DOCX and ODT in Nautilus. After 6 or 7 open files, the error still happens and the menus and tool bars are like that. ** Attachment added: "System fonts and tool bars buggy Ubuntu+LibreOffice" https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/568492/+attachment/3543906/+files/Screenshot%20from%202013-02-23%2019%3A55%3A22.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/568492 Title: Fonts corrupted on Openoffice menus and Lotus Notes 8.5 with nvidia, compiz, twinview and subpixel smoothing.
