> No, since that is the "official" API for setting a blur region.
Even it it was "official" it'd still be irrelevant since the entire approach is
insufficient for the actual task.

> Then "too bad", IMHO. We can't have a perfect approach.
Of course we can. A hint base approached on a central blurmanager (be it in
QWidget or explicitly installed) can deal with any amount of blur sources.

No. Oxygen-transparent would simply hint the window to be blurred and the
manager would invoke that into the region calculation (ie. minus opaque regions
not explicitly hinted to blur)

Probably sufficient for konsole/yakuake but rather overhead for konsole parts
in dolphin/kate etc.

Btw: to only blur an entire konsole/yakuake window (so effectively only the
translucent parts): a trivial KWin script could provide that right now.

If there's such interest, please raise hand(s).
