It's not fixed in Squeak. WarpBlt does not work with alpha 0 > < 1. Another example is rotating a systemwindow (from the halo menu), its dropshadow will be pure black. (i.e. all non-transparent pixels are rendered with their pure RGB component)
Ok, but what does this mean exactly? Previously it was possible to have rotated text. When rotating text it now shows the complete bounding box in black, not just the aliased borders. Lukas

(TransformationMorph is removed in Cuis 2.3, rotate halo button is there, but not working)

did you check in the latest version of squeak because I saw some fixes about put Morph in TextMorph? Also in Cuis 2.0 because I imagine that juan got the same transformation. Now it seems that he changed that.

I noticed a problem with transformation morphs and created a bug report:
 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.
