Getting a Font Issue in 6.7.4

Thanks but unfortunately the last solution doesn't work. Tries several times. I even uninstalled X1 and .NET 4 and reinstalled. I'm still experiencing the issue.
Reproducible use case:
- Open one of the listed emails
- Switch to Lotus Notes 8.5.x to read email
- Switch back to X1
- Just click inside columns area (to select another email, for example)... Boom!
- Font goes berserk for text in columns and menuitems under menus.

Regards
