Cosmetic Glitch when Replacing a Silver Style Combo Box by a String

[X.]

As the title says, if you replace a Silver Style Combo Box by a String (same data type), things turn ugly:

Nothing of the sort happens with the other styles as can be seen above too.

Hi X

Yea I get the same behavior in 2012 and 2013. A workaround for this would be to replace the original control or indicator with a non-silver version of the control and then replace that control with the desired silver style control. This seems to work for me.

Seems even the frameless String looses the drop-shadow effect.

(No X, I would not call that expected)

I wonder why I still bother to post this kind of things... I must be desperate for attention or something.
