Not really: it means that Qt should fill the background using the palette, in 
particular from the Window role; IMHO the bug is Qt forcing a plain background 
even if you have a brush as Window role set to something different than a 
plain color (ie a gradient or a texture).

Also, there's another bug, which is in Oxygen: as you shown, there is a 
different color between the toolbars and the rest of the application; let's 
say that some other application does something similar, or activate the 
autoFillBackground on just a part of the window, does it mean you get a 
different "color block"? I don't think you can expect all the applications to 
exactly do what the Oxygen style (nor any other style, FWIW) wants.
