That makes it consistent and should be how it works. So for konsole the default (and i know you disagree here) should be blurred when it's partly transparent.

There are valid usecases for non blur and I would say konsole belongs to them (as well the Plasma Dashboard).

Hi Thomas,

Could you elaborate a bit more on what exactly you are suggesting now? Since it "sounds" like you want a "Blur" class in which i can define the app window that "could" be blurred and the regions within that rectangle that "should" be blurred?

lets say:
class Blur
{
public:
  Blur(QRect appWindow);
  addBlurRegion(QRect region)
  // .. some more magic glue to add it to kwin
}

Where in this case the "addBlurRegion" function call would contain the Konsole KPart?

Is that what you're suggesting?

As for "Not to mention that it's bloat to link konsole against plasma in order to set a window property." .. Please do give me another option then :) You along with Martin are the folks that can make it easier.
