Tiny Font in some system menus/windows

Anyone know how to fix the tiny (1 or 2 pts) font I'm getting after upgrading to 12.10?

I get a very tiny font in the labels that pop up when I point to the icons in the dock, and in the main menu bar (at the top of the screen) for applications, as well as some system pop-ups. Other menus (e.g., system settings, tool bars in LibreOffice etc.) are fine and can be changed with tweak.

I've tried tweak, openbox and unsettings (changed fonts and changed scaling factor) -- none of the font settings have an effect on the font I mention above in red.

Maybe this is a DPI setting?

Cheers!
