Inconsistent occurences of "text with shadow" in the UI

Some places in Qt Creator display text with some kind of "1-pixel shadow". I found "Target chooser", "Pressed Menu" and "Progress Bar", but nowhere else.

Did Qt Creator originally have the text shadow in more places? It at least seems so, since the ComboBox drawing code attempts to draw a shadow but fails, since it paints text and shadow on the exact same position. There is even a theme flag "Theme::ComboBoxDrawTextShadow" which controls the infunctional combobox shadow

My question/suggestion is to either:

• enable text with shadow everywhere in the mode/tool/status bars and have a theme flag to control all of those
• remove the current occurences of text with shadow

Opinions?

Here are the shadows which I found:
