Re: What is the known issues when upgrading from natty to oneiric?

I found more than just LibreOffice tooltip colour problems and all of them were caused by odd settings in System Settings/ Application Appearance/ Colours/ Colours

Pick from the list the application with issues and make sure the Text and Background colours are not the same.
