--- Comment #44 from Paul McAuley <k...@paulmcauley.com> --- It seems that the problem is not with the code of the blur effect itself (as Vlad has already pointed out), rather that the following properties are not being set by the kwin client and in an interface to your decoration plugin in kdecoration: EffectWindow (libkwineffects/kwineffects.h) /** * Whether the window has an own shape */ Q_PROPERTY(bool shaped READ hasOwnShape) /** * The Window's shape */ Q_PROPERTY(QRegion shape READ shape) I have no idea if a QRegion is an efficient way to clip (in my ClassikStyles decoration ( https://github.com/paulmcauley/classikstyles/tree/paulmcauley/cornerblurfix/ ) I already use QPainterPaths to clip the corners of my buttons and find QPainterPaths easier to work with and to construct rounded rectangles or any shape you want). I have preliminarily added a windowShape() method to my decoration which converts a QPainterPath of my window shape to a FillPolygon, then to a Polygon, then to a QRegion (!), a shared pointer to which is then returned. I was then investigating how to glue these two together through the kdecoration and the kwin client classes, but can't continue for now due to bug 435862 preventing testing. Once we have binary decoration plugins working by being able to return a windowShape(), this functionality could be easily added to Aurorae decorations for the limited case of rounded rectangles if the Aurorae rc files were extended to have a CornerRadius property. -- You are receiving this mail because: You are watching all bug changes.
