I created a simple response window that contains only a datawindow control. Both window and datawindow have buttonface as background color.
When I run this window, both of them have the same color when not using themes and also when using all themes except Flat Design Grey.
On this theme, the window appears like this:
Since the rest of themes are painted correctly, I suspect that something is wrong with the theme.json file, but I am not sure I quite understand it yet...
The datawindow/background-color is #FFFFFF while the window/background-color is #E6E6E6.
In all other themes, window and datawindow are the same.
If I change the datawindow/background-color to #E6E6E6, the window is painted correctly....
What do you think about that?
(PB19/R1 has also the same problem)
