I noticed a problem with transformation morphs and created a bug report: Â http://code.google.com/p/pharo/issues/detail?id=2207 The problem seems to be that the transformation morph creates a black rectangle on the rotated clipping bounds. I does not only happen with TextMorphs but also with (some) other morphs. I tried to convert the TextMorph to a SketchMorph and the same happens there. I have no idea how to fix that problem. I need a solution because eCompletion rotates some text by 90, which is currently not possible. | stringMorph transformationMorph | stringMorph := 'vertical text' asMorph. transformationMorph := TransformationMorph new asFlexOf: stringMorph. transformationMorph angle: Float pi / 2. transformationMorph position: 5@5. transformationMorph openInWorld.
