Don't you just love bugs? :)

Steps to reproduce:

1. open Internet Explorer 7
2. go to any page (required only if blank page opens when IE7 starts)
3. press Ctrl+ (increases size of text and images)
4. open another tab
5. go back to first tab
6. text is scrambled

Not reproducible every time, try it several times, and it should reproduce.
