Could you test with hardware acceleration disabled:

Then could you test with a fresh profile:

I created a new profile and went to the kingworldnews.com and 
I didn't get the graffiti. What should I do next?

Thanks 

Dave

If HWA is not involved, it could be an issue with one of your add-on (safe mode will help) or a bad pref.
You can try to reset the prefs of your current profile (make a backup copy before).
