This can be noticed on menu bar, where text-shadow is multiplied (showed as a stronger shadow). Another issue is that when you preview tab other than active, text on active one is doubled; the original one is overlaped by background text. Reproducible: Always Steps to Reproduce: 1. Open two or more tabs 2. Preview tab other than active

After disabling Aero Glass, it is working OK.

I talked about this with Steven Horlander a few weeks ago - the most noticeable bug is that the semi-transparent tabs cause the text to overlay and the text layout is slightly different.

This bug actually is a bit worse. When the location bar and search bar are styled slightly transparent (which they are meant to be to match Windows theme), the location bar from the current tab shows through. The image I provided shows a severe case, where the safe domain and long url show through. It looked like this in a nightly, when glass was not disabled again.

This is still issue. Furthermore, when hovering preview titlebar swithces to original state before showing preview, plus close button on first tab appears for one second when switch between tabs.
