Can you attach a screenshot?

Make sure you allow pages to choose their own fonts as this affects iconic fonts.

  • Settings -> General -> Language and Appearance -> Fonts -> Advanced
    [X] "Allow pages to choose their own fonts, instead of your selections above"

Try disabling any third-party antivirus or security software.

Does it still happen in Troubleshoot Mode?
