Hi Pino,
well the thing is that, by default, autofillbackground is set to false, 
meaning: the background for widgets is copied from the mainWidow 
background.

if you set it to true, well it means you do want to use a solid color 
for your background, and the style should not (and will not) override 
that with its own fancy stuff. Correct ?
Now the question is: does okular really wants "autofillbackground" set 
to true in all cases ?
If it wants, then I will not try to go around it in the style, cause 
this is a valid (and supported) choice of the app.
If it does not, then, set it to false, and you get the nice oxygen 
background, as expected.

So that all in all, I don't think my patch is a workaround to hide a Qt 
(or style) bug.
Does the above make sense ?

Now, for the complete story: in QAbstractScrollArea, autofillbackground 
is set to true by default (on the viewport widget), and hard/impossible 
to set to false. This I fixed in oxygen style a couple of days ago (to 
address a visual bug in plasma "mouse actions" dialog). But the okular 
case is a different issue (where autofillbackground is set to false 
_manually_, and IMO should not, in some cases).
