It seems you are right, and it looks like a TScrollBar bug. Very easy to
reproduce. Simply place one vertical and one horizontal scrollbar on a
Form. Set the Form.Color to clBlack. Poof, your scrollbars disappear
(strangely enough except for the left and top scroll button). All GTK2
theme painting of the scrollbar is ignored by LCL.
Looking at TCustomScrollBar, it seems they do lots of odd WinAPI-style
trickering in just creating the component, so I have no clue what's
actually going on. But I'll play around some more.
