I actually did have it "fixed", and it was in a couple of the ProLCD betas, but I decided to get rid of the text. The fix was to make the bevel transparent and act as a light highlight overlaying the flat grey background. Because the text is under the bevel, the text would then show through. Unfortunately it didn't show through very well, and the same highlight was applied to the text as to the metal window.
Hm, I don't know if that made any sense or not. Basically it's possible to get the text, but it won't look very pretty. The only theme I've seen that uses this hack fix and doesn't look bad is Neos, but it's still noticable if you look for it.
