I'm on a ThinkPad X1 Carbon 3rd gen and I've installed Ubuntu 14.10 using the whole disk. Initially after install, everything was just fine, but after running 'aptitude upgrade -y', menu items and strings in UI (button labels, labels, ...) are incorrectly displayed.
The attached image is a screenshot of the select file dialog, opened while reporting this bug. In the left pane, the text for the selected entry should read "Bilder", and the third entry from the top should say "ceda". In the list of files, the bottom entry should say "x1-x11-issue-02b.png' (and date columns should say 'tisdag').
As I move the mouse over the left pane (folder/favorite selection), the bottom line changes back and forth between the correct "Hämtningar" and incorrect "Hämtninga". A similar pattern goes for the Open button: you can see that the text right now is "Öppna" but the p characters are drawn with different color. Once hovering over the button, it's drawn correctly.
Things I'd like to try:
* use older video driver - but I don't know how to do that
* use Xfce
Status changed to 'Confirmed' because the bug affects multiple users.
